I am doing the following thing to replace some part of the string. I want to replace all three occurence of the string but it is not working.
var hdnval = document.getElementById("hdnColgval").value = response;
$("#ddcolgs").val($("#ddcolgs").val().replace(/'+hdnval+'/g, response));
You are trying to append a string to a regex which will cause errors. If you are simply replacing strings, try this:
var hdnval = document.getElementById("hdnColgval").value = response;
$("#ddcolgs").val($("#ddcolgs").val().replace(hdnval, response));
If the value of #hdnColgval is supposed to be a regex expression, use this:
var hdnval = document.getElementById("hdnColgval").value = response;
var regex = new Regex(hdnval, 'g');
$("#ddcolgs").val($("#ddcolgs").val().replace(regex, response));
test(), like this: '|lcol~-1|lcol~-1'.test('-1') which will return true/false depending on whether -1 was found.You can't create a regular expression from a variable in that way.. try:
.replace(new RegExp(hdnval, 'g'), response);
To use your variable in the regex, use the new Regexp method:
var hdnval = document.getElementById("hdnColgval").value,
re = new RegExp(hdnval, "g");
$("#ddcolgs").val(function(i,v) {
return v.replace(re, response);
});
Your implementation is almost correct, jssut remove the quotes. You don't need them
var hdnval = document.getElementById("hdnColgval").value = response;
$("#ddcolgs").val($("#ddcolgs").val().replace(/hdnval/g, response));
$("#ddcolgs").val(function(i, val) {
return val.replace(RegExp(hdnval,'g'), response);
}
