I need to replace hypen from string using Javascript but as per my code its not working.
function replace(){
var str='20-03-2019';
str.replace(/-/g,'/');
console.log(str);
}
replace();
Here I need to replace hypen(-) with / and output should like 20/03/2019.


String is immutable, so you need to do :
function replace(){
var str='20-03-2019';
str = str.replace(/-/g,'/');
alert('date ' + str);
}
replace();

my replace function only replace one character.
My Code example
const string = "What,Yo,Yes"
string.replace(","," ")
Console
"What Yo,Yes"

Something like this:
const string = "What,Yo,Yes";
console.log(string.replace(/,/g," "));
Alternatively, you can use replaceAll, like this:
const string = "What,Yo,Yes";
console.log(string.replaceAll(","," "));

I am new in Javascript. I have a little problem:
I have a string like this "thisIsATestString".
So how can I make this string to "This Is A Test String"?

Already answered: Convert camelCaseText to Sentence Case Text
You should have searched for "camel case to sentence."

This should help to resolve it.
const sentence = 'thisIsATestString';
const updatedSentenec = (sentence[0].toUpperCase() + sentence.slice(1)).split(/(?=[A-Z])/).join(' ')

Try this:
"thisIsATestString".replace(/(^\w|[A-Z])/g, function (match) {
return ' ' + match.toUpperCase();
}).trim();

In JavaScript, I need to find a substring between &J= and Key using regex and remove it from my url which could contain several substrings.
Here is my url:
SID=18608202881669&Act=432&Mode=1&CLk=T&Key58=6003&dotnetdll=TopCoConfigurator.dll&dotnetfunc=CasingSizeSummary&SID=18608202881669&F=&J=CasingSize/CasingSizeSummary.asp&Key58=6003&ccs_casingsizeid=6003
Thanks

You can learn Regular Expression here and code for your problem is:
Here you go:
SID="18608202881669&Act=432&Mode=1&CLk=T&Key58=6003&dotnetdll=TopCoConfigurator.dll&dotnetfunc=CasingSizeSummary&SID=18608202881669&F=&J=CasingSize/CasingSizeSummary.asp&Key58=6003&ccs_casingsizeid=6003";
var re = /&J=(.*?)&Key/;
SID = SID.replace(re, '');
alert(SID);

I am trying to extract a string from within a larger string where i need to get the value only inside the brackets.
var str = 'ajay kumar (68766)';

Try this:
var str = 'ajay kumar (68766)';
str = str.slice(str.indexOf('(')+1, str.indexOf(')'));

How about using a regular expression?
var str = 'ajay kumar (68766)';
var output = str.replace(/^[\s\S]*?\((\d+)\)[\s\S]*?$/, '$1');
