Selecting entire string using Regex

Question

I need help with a regex to select this entire string %2526_ga%253d1.193373933.1506621463.1391436765&

this exact match is always there: %2526_ga%253d

there's always a random number like this, but don't focus on the period since there's other periods later in the URL similar to this: 1.193373933.1506621463.1391436765&

This is what I have so far:

var str = window.location.search.match('_ga%253d');
alert(str);

can the number part be any length or does it have the same amount of digits between periods every time? Does it always end with a &? — Starscream1984

that's a good question. I'll have to test and check a couple times to see if the length of the number changes. — Evan

If you want your prefix plus any digits full stops until the first etcetera the regex below should do

/_ga%253d'([0-9\.])+&/
