jQuery issue with string split

Question

I have a string as below

var a = "M=1234&b=sdaks&c=sdkssad&strXML=<a><b mode="abc"><c>string content</c></b></a>"

Then I split it with &

var b = a.split('&');

Then further more I split b with = in loop and append to the form

$.each(b, function (index) {
        var paramsV = b[index].split('=');
        frm.append('<input type="hidden" name="' + paramsV[0] + '" value="' + paramsV[1] + '" /> ');
    });

But when it split with = that time it is splitting result string which have = inside the string and it is splitting that too. I would like to know how I can stop splitting the result string.

The issue is that the split string still has the '=' symbol? — itsmichaelwang

there seems to be a typo. can show us what is your expected and current output? — Dinesh undefined

I suggest to reduce your efforts by properly encoding url safe parameters, so that decoding them will be lot more easier — user2575725

I this what you want to achieve, Use .split(/=(.+)/) to only split the first =

Also notice that when you try to enter paramsV[1] that has a " inside it, it will break the original code of Input, that's why I replaces it with .replace(/\"/g, "''")

var a = 'M=1234&b=sdaks&c=sdkssad&strXML=<a><b mode="abc"><c>string content</c></b></a>'

var b = a.split('&');
var frm = $(".frm")
$.each(b, function(index) {
  var paramsV = b[index].split(/=(.+)/);
  frm.append('<input type="" name="' + paramsV[0] + '" value="' + paramsV[1].replace(/\"/g, "''") + '" /> ');
});

<div class="frm"></div>

You have made a mistake in variable declaration. Inside double quotes you need to use single quotes. And you need to use regular expression like .split(/=(.+)?/). See the output below.

$(function(){
var a = "M=1234&b=sdaks&c=sdkssad&strXML=<a><b mode='abc'><c>string content</c></b></a>";
var b = a.split('&');
$.each(b, function (index) {
        var paramsV = b[index].split(/=(.+)?/);
        console.log('<input type="hidden" name="' + paramsV[0] + '" value="' + paramsV[1] + '" /> ');
    });
});

var a = "M=1234&b=sdaks&c=sdkssad&strXML=<a><b mode='abc'><c>string content</c></b></a>";
    var b = a.split('&');
    $.each(b, function (index) {
        var index1 = b[index].indexOf("=")
        var markup ='<input type="hidden" name="' + b[index].substring(0, index1) + '" value="' + b[index].substring(index1) + '" /> ';
        console.log(markup);
    });
