Example:
I have string like this : http://example.com/path/?value1=123&value2=334&value3=x2y&value4=2bx
How can I exactly replace string above with exact value I want.
Such as, I want to replace to change value2=334 to value2=b2y
I mean that the current value of value2 will be replaced with b2y.
I use Jquery only. Thank for your support.
1- for getting query param from any url
function getQueryVariable(url, variable) {
var query = url.substring(1);
var vars = query.split('&');
for (var i=0; i<vars.length; i++) {
var pair = vars[i].split('=');
if (pair[0] == variable) {
return pair[1];
}
}
return false;
}
Example var url = 'http://www.example.com/hello.png?w=100&h=101&bg=white';
var w = getQueryVariable(url, 'w');//100
var h = getQueryVariable(url, 'h');//101
var bg = getQueryVariable(url, 'bg');//white

2- Set the Query Param of a url
function updateQueryStringParameter(uri, key, value) {
var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");
var separator = uri.indexOf('?') !== -1 ? "&" : "?";
if (uri.match(re)) {
return uri.replace(re, '$1' + key + "=" + value + '$2');
}
else {
return uri + separator + key + "=" + value;
}
}
