JavaScript One of the ways to get URL parameters

If the address bar URL is: abc. html? m = tomms & c=allsearchlist & pageNo=1 & pageNum=20 & text=1

<script>
  //JavaScript Get url , and put url The method that changes the parameters in the, arr The value of the array is the value of each parameter 
  var url = window.document.location.href.toString();
  var u = url.split("?");
  var arr = [];
  if(typeof(u[1]) == "string"){
    u = u[1].split("&");
    for(var i in u){
      var a = (u[i].split("="));
      arr[a[0]] = a[1];
    }
  }
</script>

Note: When URL has Chinese, the Chinese parameters will be garbled!
