Javascript function date argument

Date() constructor

The Date() constructor creates Date objects. When called as a function, it returns a string representing the current time.

Try it

Syntax

new Date() new Date(value) new Date(dateString) new Date(dateObject) new Date(year, monthIndex) new Date(year, monthIndex, day) new Date(year, monthIndex, day, hours) new Date(year, monthIndex, day, hours, minutes) new Date(year, monthIndex, day, hours, minutes, seconds) new Date(year, monthIndex, day, hours, minutes, seconds, milliseconds) Date() 

Note: Date() can be called with or without new , but with different effects. See Return value.

Parameters

There are five basic forms for the Date() constructor:

No parameters

When no parameters are provided, the newly-created Date object represents the current date and time as of the time of instantiation. The returned date’s timestamp is the same as the number returned by Date.now() .

Time value or timestamp number

An integer value representing the timestamp (the number of milliseconds since midnight at the beginning of January 1, 1970, UTC — a.k.a. the epoch).

Date string

A string value representing a date, parsed and interpreted using the same algorithm implemented by Date.parse() . See date time string format for caveats on using different formats.

Date object

An existing Date object. This effectively makes a copy of the existing Date object with the same date and time. This is equivalent to new Date(dateObject.valueOf()) , except the valueOf() method is not called.

When one parameter is passed to the Date() constructor, Date instances are specially treated. All other values are converted to primitives. If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp.

Individual date and time component values

Given at least a year and month, this form of Date() returns a Date object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value ( 1 for day and 0 for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. Date.UTC() accepts similar parameters but interprets the components as UTC and returns a timestamp.

If any parameter overflows its defined bounds, it «carries over». For example, if a monthIndex greater than 11 is passed in, those months will cause the year to increment; if a minutes greater than 59 is passed in, hours will increment accordingly, etc. Therefore, new Date(1990, 12, 1) will return January 1st, 1991; new Date(2020, 5, 19, 25, 65) will return 2:05 A.M. June 20th, 2020.

Similarly, if any parameter underflows, it «borrows» from the higher positions. For example, new Date(2020, 5, 0) will return May 31st, 2020.

Integer value representing the year. Values from 0 to 99 map to the years 1900 to 1999 . All other values are the actual year. See the example.

Integer value representing the month, beginning with 0 for January to 11 for December.

Integer value representing the day of the month. Defaults to 1 .

Integer value between 0 and 23 representing the hour of the day. Defaults to 0 .

Integer value representing the minute segment of a time. Defaults to 0 .

Integer value representing the second segment of a time. Defaults to 0 .

Integer value representing the millisecond segment of a time. Defaults to 0 .

Return value

Calling new Date() (the Date() constructor) returns a Date object. If called with an invalid date string, or if the date to be constructed will have a timestamp less than -8,640,000,000,000,000 or greater than 8,640,000,000,000,000 milliseconds, it returns an invalid date (a Date object whose toString() method returns «Invalid Date» and valueOf() method returns NaN ).

Calling the Date() function (without the new keyword) returns a string representation of the current date and time, exactly as new Date().toString() does. Any arguments given in a Date() function call (without the new keyword) are ignored; regardless of whether it’s called with an invalid date string — or even called with any arbitrary object or other primitive as an argument — it always returns a string representation of the current date and time.

Examples

Several ways to create a Date object

The following examples show several ways to create JavaScript dates:

const today = new Date(); const birthday = new Date("December 17, 1995 03:24:00"); // DISCOURAGED: may not work in all runtimes const birthday = new Date("1995-12-17T03:24:00"); // This is standardized and will work reliably const birthday = new Date(1995, 11, 17); // the month is 0-indexed const birthday = new Date(1995, 11, 17, 3, 24, 0); const birthday = new Date(628021800000); // passing epoch timestamp 

Passing a non-Date, non-string, non-number value

If the Date() constructor is called with one parameter which is not a Date instance, it will be coerced to a primitive and then checked whether it’s a string. For example, new Date(undefined) is different from new Date() :

.log(new Date(undefined)); // Invalid Date 

This is because undefined is already a primitive but not a string, so it will be coerced to a number, which is NaN and therefore not a valid timestamp. On the other hand, null will be coerced to 0 .

.log(new Date(null)); // 1970-01-01T00:00:00.000Z 

Arrays would be coerced to a string via Array.prototype.toString() , which joins the elements with commas. However, the resulting string for any array with more than one element is not a valid ISO 8601 date string, so its parsing behavior would be implementation-defined. Do not pass arrays to the Date() constructor.

.log(new Date(["2020-06-19", "17:13"])); // 2020-06-19T17:13:00.000Z in Chrome, since it recognizes "2020-06-19,17:13" // "Invalid Date" in Firefox

How to pass and call Snowflake stored procedure date argument in underlying SELECT statement as a column

Binding a variable to a SQL statement allows you to use the value of the variable in the statement.

CREATE OR REPLACE PROCEDURE test1 (TEST_DATE VARCHAR) RETURNS VARCHAR NOT NULL LANGUAGE javascript EXECUTE AS CALLER AS $$ var sql_stmt = `select ID ,Value , :1 as TestDate , to_varchar(CURRENT_TIMESTAMP()) AS CreateDate from Table;`; var statement = snowflake.createStatement( ); var rs = statement.execute(); . $$; 

I think Binding like mentioned above is the more proper method, but you could also use string formatting its a bit more readable.

CREATE OR REPLACE PROCEDURE test1 (TEST_DATE VARCHAR) RETURNS VARCHAR NOT NULL LANGUAGE javascript EXECUTE AS CALLER AS $$ var prod = TEST_DATE; var sql_stmt = `select ID ,Value ,'$' as TestDate , to_varchar(CURRENT_TIMESTAMP()) CreateDate from Table;`; var statement = snowflake.createStatement( ); var rs = statement.execute(); rs.next(1); //return rs.getColumnValue(1); return rs.getColumnValue(3); $$;

How to set a default date parameter to pass to ajax get call in JavaScript, on selecting date value it should change

You can use Window.localStorage to check if the page is reloaded for the first time or not .By using this you need to setItem in localStorage which will be used to check if the item is set or not depending upon that you can perform required operation.

So, your jquery code will look like below :

(function() < $.fn.dataTable.ext.errMode = 'none'; $("#srchVehDtPicker").datepicker(< format: "yyyy-mm-dd", autoclose: true >); if (window.localStorage) < //checking value in local storage if (!localStorage.getItem('firstLoad')) < //settting value in localstorage localStorage['firstLoad'] = true; var utc = new Date().toJSON().slice(0, 10); document.getElementById("DtPicker").value = utc; console.log("First time load"); // calling ajax funtion with default parametr. attendance(utc); >else < //do something console.log("Not loaded first time"); >> >()); 

Update 1 : As i have already said that you can use sessionStorage to store the value of date and and whenever your page reload check that store data against the default value of date if differ then take sessionStorage value else take default value .Your code will look like below :

(function() < $.fn.dataTable.ext.errMode = 'none'; $("#srchVehDtPicker").datepicker(< format: "yyyy-mm-dd", autoclose: true >); var utc = new Date().toJSON().slice(0, 10); document.getElementById("DtPicker").value = utc; //if there is some value in session if (window.sessionStorage) < //getting current value in sessionStorage var date_value = sessionStorage.getItem("date"); //value fetch is equal to current date if (date_value == utc) < //setting current value sessionStorage.setItem("date", utc); //calling function attendance(utc); >else if (date_value != utc) < //setting session storage with updated value sessionStorage.setItem("date", date_value); >> else < //onload setting session sessionStorage.setItem("date", utc); attendance(utc); >>()); // On button click search funtion is called where selected date is collected passed to ajax as parameter function SearchDate() < // taking the value from input date value on button click. var searchdate = $("#DtPicker").val(); var utc = searchdate.toString(); //setting value in session sessionStorage.setItem("date", utc) // calling ajax value with a value as a parameter. attendance(utc); >

(Above code is not tested but , it should work.Sorry for any syntax error)
