Javascript list all objects by id start with

In your case : Solution 3: Because you didn’t tag jQuery, and you probably don’t need it, my suggestion would be to add a class to these elements when you create them. HTML JS jsfiddle demo Solution 2: Today you can select elements with the same id attribute this way: Or this way with jQuery: CSS selector should work also for all elements with .

Find all elements whose id begins with a common string

Using jQuery you can use the attr starts with selector:

Using modern browsers, you can use the CSS3 attribute value begins with selector along with querySelectorAll :

var dates = document.querySelectorAll('*[id^="createdOnID"]'); 

But for a fallback for old browsers (and without jQuery) you’ll need:

var dateRE = /^createdOnid/; var dates=[],els=document.getElementsByTagName('*'); for (var i=els.length;i--;) if (dateRE.test(els[i].id)) dates.push(els[i]); 

You should have just used simple CSS selector together with JavaScript ‘s .querySelectorAll() method.

var dates = document.querySelectorAll('[id^="createdOnId"]'); 

Because you didn’t tag jQuery, and you probably don’t need it, my suggestion would be to add a class to these elements when you create them. Then use the getElementsByClassName() function that’s built into most browsers. For IE you would need to add something like this:

if (typeof document.getElementsByClassName!='function') < document.getElementsByClassName = function() < var elms = document.getElementsByTagName('*'); var ei = new Array(); for (i=0;i> > else if (elms[i].className) < ecl = elms[i].className.split(' '); for (j=0;j> > > return ei; > > 

Get multiple elements by Id

If you can change the markup, you might want to use class instead.

var elements = document.getElementsByClassName("test"); var names = ''; for(var i = 0; i < elements.length; i++) < names += elements[i].name; >document.write(names); 

Today you can select elements with the same id attribute this way:

document.querySelectorAll('[id=test]'); 

CSS selector #test < . >should work also for all elements with id = «test» . Вut the only thing: document.querySelectorAll(‘#test’) (or $(‘#test’) ) — will return only a first element with this id. Is it good, or not — I can’t tell . But sometimes it is difficult to follow unique id standart .

For example you have the comment widget, with HTML-ids, and JS-code, working with these HTML-ids. Sooner or later you’ll need to render this widget many times, to comment a different objects into a single page: and here the standart will broken (often there is no time or not allow — to rewrite built-in code).

As oppose to what others might say, using the same Id for multiple elements will not stop the page from being loaded, but when trying to select an element by Id, the only element returned is the first element with the id specified. Not to mention using the same id is not even valid HTML.

That being so, never use duplicate id attributes. If you are thinking you need to, then you are looking for class instead. For example:

Notice how each given element has a different id, but the same class. As oppose to what you did above, this is legal HTML syntax. Any CSS styles you use for ‘.mydiv’ (the dot means class) will correctly work for each individual element with the same class.

With a little help from Snipplr, you may use this to get every element by specifiying a certain class name:

function getAllByClass(classname, node) < if (!document.getElementsByClassName) < if (!node) < node = document.body; >var a = [], re = new RegExp('\\b' + classname + '\\b'), els = node.getElementsByTagName("*"); for (var i = 0, j = els.length; i < j; i++) < if (re.test(els[i].className)) < a.push(els[i]); >> > else < return document.getElementsByClassName(classname); >return a; > 

The above script will return an Array, so make sure you adjust properly for that.

Javascript : get all the object where id is like log_XXXX, var matches = []; var elems = document.getElementsByTagName(«*»); for (var i=0; i

Javascript : get all the object where id is like log_XXXX

// DOM collection as proper array const matches = Array.from(document.querySelectorAll('[id^=log_]')); 

// Use Array.prototype.slice to turn the DOM collection into a proper array var matches = [].slice.call(document.querySelectorAll('[id^=log_]')); 

Really Old Browsers, no jQuery:

var matches = []; var elems = document.getElementsByTagName("*"); for (var i=0; i //matches now is an array of all matching elements. 

Ok, here’s a straight JavaScript answer:

// a handy function to aid in filtering: // takes an array and a function, returns another array containing // only those elements for which f() returns true function filter(a, f) < var ret = []; for (var i=0; ireturn ret; > // this collects all elements in the current document var elements = document.getElementsByTagName("*"); // and this filters out all but those that match our pattern var logElements = filter(elements, function(el) < return /log_/.test(el.id) >); // simple expression 

It would be best to use a JS framework to accomplish this because they have advanced DOM selector functions that make what you want to do incredibly easy. There are many to choose from but the more popular are jQuery, Prototype, MooTools, and Dojo.

How to convert id’s in array of objects to a list JavaScript

If you want to extract values from a collection of objects, don’t use filter . Use map .

let list = [ < id: 1 >, < id: 3 >, < id: 23 >, < id: 16 >];let data = list.map((obj) => obj.id); console.log(data);

var list = [ < id: 1 >, < id: 3 >, < id: 23 >, < id: 16 >];var data = list.map(function(obj) < return obj.id; >); console.log(data);

JavaScript — Find multiple objects by IDs existing in prefined list from, Use a .filter : The filter() method creates a new array with all elements that pass the test implemented by the provided function. filter.

JavaScript Select All HTML Elements Whose ID Start With Same String

In this tutorial we will see how to Select All HTML Elements Whose ID Start With Same String using JavaScript. The querySelectorAll and substring matching attribute selector are used for this.

HTML Code

HTML Code is given below, This code contains three different HTML elements. One H1 heading, One Paragraph element and One Span Tag. All these tags have different ids. But id of two tags start with same term (HTCS). When button is clicked the JavaScript code will only select two elements whose id start with same string.

      
Select All Elements With ID that starts with "HTCS".
 
Heading
 
Paragraph
 Span Tag Get Elements   

querySelectorAll() Method

The querySelectorAll() Method is used to select or target all HTML elements that matches with specified CSS Selector.

The querySelectorAll() Method will return a list of all HTML elements which match the specified group of selectors.

In this example we have used Substring Matching Attribute Selector inside querySelectorAll() Method.

Substring Matching Attribute Selector

There are three Substring Matching Attribute Selectors. We have used [attribute^=»value»] in this example, which match the defined value with the prefix of value of id attribute.

In this example, the value of id attribute is matched with the defined string and the matched elements are selected whose id start with that defined string.

It is also known as Attribute Starts With Selector.

JavaScript Code

In this example, main function selectElems() will be executed on button click. Then querySelectorAll() Method will only select those elements whose id start with the term ‘HTCS’.

querySelectorAll() Method does this with the help of [attribute^=»value»] selector. The for loop is then used to change background color of all selected elements one by one.

Take a look at the code given below.

Take all id starting by jquery

Solution 2: If you want only the number, then replace by If you want total id then as @satpal has suggested Solution 3: You need to extract number from id property so use instead of Solution 4: If you wants to take the id’s then use , Solution: You are trying to get tag within tag, remove the find part since its already contains collection of tags(assuming elements with id prefix are select tags).

Get and save all id start with using javascript

I have structure like this

  I want to get a number of form like 1 , 2 , . n . I try using this code just to get all id .

var num = new Array(); var elems = $('div[id^=form]'); for (var i=0; i alert(num); 

But it returns [object HTMLdivElement] . What is wrong? How can I get just the number?

Use map() method like following.

var num = $('div[id^=form]').map(function() < var if(!isNaN(id)) return +id; // + to convert string to num >).get(); alert(num);

If you want only the number, then

If you want total id then as @satpal has suggested

You need to extract number from id property ****

var num = new Array(); var elems = $('#form-input div[id^=form]');for (var i = 0; i < elems.length; i++) < num.push(elems[i].id.replace(/\D/g, '')); >console.log(num);

If you wants to take the id’s then use map() ,

$('#form-input > div').map(function() < console.log(this.id); >);

Find all select boxes with id or name starting with a specific string [duplicate]

I am trying to push all select elements starting with specific id or name and tried the following but it doesn’t seem to work:

var IDs = []; $("#dynamic_field [id^='product_id']").find("select").each(function()< IDs.push(this.id); >); alert(IDs.length); 

If I don’t specify the specific select id or name it works:

var IDs = []; $("#dynamic_field").find("select").each(function()< IDs.push(this.id); >); alert(IDs.length); 

You are trying to get select tag within select tag, remove the find part since its already contains collection of select tags(assuming elements with id prefix product_id are select tags ). If there are other elements with id prefix product_id then combine select with the attribute starts with selector.

var IDs = []; $("#dynamic_field select[id^='product_id']").each(function()< IDs.push(this.id); >); alert(IDs.length); 

You can use jQuery map() method to generate the array where use get() method to convert jQuery collection to array.

var IDs = $("#dynamic_field select[id^='product_id']").map(function()< return this.id; >).get(); 

or using jQuery.map method.

var IDs = $.map($("#dynamic_field select[id^='product_id']"), ele => ele.id); 

Jquery find all ids starting with a string?, Hi, I have a confusion, I have a scenario like this :

Jquery select all checkbox of a div whose id starts with «idName»

Following code works fine for single variable idName

$('#' +idName+ ' input:checkbox').each(function()

where idName is a variable having id of div, for instance abc But now idName can have any values including abc1, abc2 etc (i.e. abc_). I used following code:

$('[id^="'+idName+'"] input:checkbox').each(function()

But it is not working. Can anybody point it out where I am going wrong? Sorry for not arranging for a fiddle

 $("input:checkbox[id="+idName+"]").attr('checked',false);
