JS Handling Skills for Jumping Values in Static Page html

This article provides an example of JS processing techniques for jumping values in static page html.Share it for your reference, as follows:

In html by'?'Pass-by value:

<a href="index2.html?name=caoy"> Static value transfer </a>

Receive in page index2.html that jumps to:

var name=UrlParm.parm("name");

The code is as follows:

index.html:

<script type="text/javascript" src="getUrlParam.js"></script>
<a href="index2.html?name=caoy"> Static value transfer </a>

index2.html:

<script type="text/javascript">
  var name=UrlParm.parm("name");
  alert(name);
</script>

getUrlParam.js:

UrlParm = function() { // url parameter 
 var data, index;
 (function init() {
  data = [];
  index = {};
  var u = window.location.search.substr(1);
  if (u != '') {
   var parms = decodeURIComponent(u).split('&');
   for (var i = 0, len = parms.length; i < len; i++) {
    if (parms[i] != '') {
     var p = parms[i].split("=");
     if (p.length == 1 || (p.length == 2 && p[1] == '')) {// p | p=
      data.push(['']);
      index[p[0]] = data.length - 1;
     } else if (typeof(p[0]) == 'undefined' || p[0] == '') { // =c | =
      data[0] = [p[1]];
     } else if (typeof(index[p[0]]) == 'undefined') { // c=aaa
      data.push([p[1]]);
      index[p[0]] = data.length - 1;
     } else {// c=aaa
      data[index[p[0]]].push(p[1]);
     }
    }
   }
  }
 })();
 return {
  //  Get parameters , Similar request.getParameter()
  parm : function(o) { // o:  Parameter name or order 
   try {
    return (typeof(o) == 'number' ? data[o][0] : data[index[o]][0]);
   } catch (e) {
   }
  },
  // Get Parameter Group ,  Similar request.getParameterValues()
  parmValues : function(o) { // o:  Parameter name or order 
   try {
    return (typeof(o) == 'number' ? data[o] : data[index[o]]);
   } catch (e) {}
  },
  // Does it contain parmName parameter 
  hasParm : function(parmName) {
   return typeof(parmName) == 'string' ? typeof(index[parmName]) != 'undefined' : false;
  },
  //  Get parameters Map , Similar request.getParameterMap()
  parmMap : function() {
   var map = {};
   try {
    for (var p in index) { map[p] = data[index[p]]; }
   } catch (e) {}
   return map;
  }
 }
}();

This allows you to jump values through html
