javascript - Jquery progress bar: How to activate it on document loading/initiation -


below have jquery progress bar (see code). loads using start/stop button function. want load automatically first thing before other elements of website loads, since progress bar after all. want start moment web page starts load , want stop moment content of webpage starts showing. (just show progress during white screen waiting period...)

my code:

<script type="text/javascript"> var pct=0; var handle=0; function update(){     $("#progressbar").reportprogress(++pct);     if(pct==100){             clearinterval(handle);             $("#run").val("start");             pct=0;     } } jquery(function($){     $("#run").click(function(){             if(this.value=="start"){                     handle=setinterval("update()",100);                     this.value="stop";             }else{                     clearinterval(handle);                     this.value="start";             }     });     $("#reset").click(function(){             pct=0;             $("#progressbar").reportprogress(0);     }); }); </script>

html:

<div id="progressbar"></div> <input type="button" id="run" value="start"></input> <input type="button" id="reset" value="reset"></input>

css:

#progressbar{     border:1px solid black;     width:200px;     height:20px;     position:relative;     color:black; } /* color bar */ #progressbar div.progress{     position:absolute;     width:0;     height:100%;     overflow:hidden;     background-color:#369; } /* text on bar */ #progressbar div.progress .text{     position:absolute;     text-align:center;     color:white; } /* text off bar */ #progressbar div.text{     position:absolute;     width:100%;     height:100%;     text-align:center; }

would appreciate help. thanks

then should use

$(window).load(function () {                  //write progress bar function here..      });
