This article introduces the example of page jump progress bar based on javascript and shares it with everyone for your reference. The specific content is as follows
Rendering:
Specific code:
<HTML> <HEAD> <TITLE>open代码</TITLE> <SCRIPT type=text/javascript> <!-- var ie5 = (document.all && document.getElementsByTagName); var step = 0; function setSB(v, el, inforEl, message) { if (ie5 || document.readyState == "complete") { filterEl = el.children[0]; valueEl = el.children[1]; if (filterEl.style.pixelWidth > 0) { var filterBackup = filterEl.style.filter; filterEl.style.filter = ""; filterEl.style.filter = filterBackup; } filterEl.style.width = v + "%"; valueEl.innerText = v + "%"; inforEl.innerText = message; } } function setSBByStep(v, el, inforEl, message) { if (ie5 || document.readyState == "complete") { step = step + v; filterEl = el.children[0]; valueEl = el.children[1]; if (filterEl.style.pixelWidth > 0) { var filterBackup = filterEl.style.filter; filterEl.style.filter = ""; filterEl.style.filter = filterBackup; } filterEl.style.width = step + "%"; valueEl.innerText = step + "%" inforEl.innerText = message; } } function fakeProgress(v, el) { if (v >= 101) location.href="http://www.jb51.net"; else { setSB(v, el, infor, "页面正在跳转中,请稍候..."); window.setTimeout("fakeProgress(" + (v + 1) + ", document.all['" + el.id + "'])", 10); } } //--> </SCRIPT> <SCRIPT language=javaScript> </SCRIPT> </HEAD> <BODY bgColor=#f9f9f9 topMargin=100 onload=fakeProgress(0,sb)> <P> </P> <P> </P> <P> </P> <!-- Status Bar Starts --> <DIV align=center> <DIV id=sb style="BORDER-RIGHT: #ffffff 1px solid; BORDER-TOP: #ffffff 1px solid; BACKGROUND: #99ccff; BORDER-LEFT: medium none; WIDTH: 400px; BORDER-BOTTOM: #cccccc 1px solid; HEIGHT: 14px; TEXT-ALIGN: left"> <DIV id=sbChild1 style="FILTER: Alpha(Opacity=0, FinishOpacity=80, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0); OVERFLOW: hidden; WIDTH: 100%; POSITION: absolute; HEIGHT: 12px"> <DIV style="BACKGROUND: #000000; WIDTH: 100%" ;height:12px; overflow: hidden></DIV> </DIV> <DIV style="FONT-SIZE: 10px; WIDTH: 400px; COLOR: white; FONT-FAMILY: arial; POSITION: absolute; HEIGHT: 14px; TEXT-ALIGN: center"></DIV> </DIV> <!-- Status Bar Ends --> <P></P> <DIV id=infor style="FONT-SIZE: 11px; WIDTH: 100%; COLOR: #999999; FONT-FAMILY: arial; POSITION: relative; HEIGHT: 14px; TEXT-ALIGN: center"></DIV> </DIV> </BODY> </HTML>
Code 2 is also very good, the running effect is as follows
Code sharing:
<html> <head> <script language="javascript"> function setSB(v, el) { var ie5 = (document.all && document.getElementsByTagName); if (ie5 || document.readyState == "complete") { filterEl = el.children[0]; valueEl = el.children[1]; filterEl.style.width = v + "%"; valueEl.innerText = v + "%"; } } function fakeProgress(v, el) { if (v > 100) location.href = "http://www.jb51.net/"; else { setSB(v, el); window.setTimeout("fakeProgress(" + (++v) + ", document.all['" + el.id + "'])", 20); } } </SCRIPT> </head> <body onload="fakeProgress(0, sb)" topmargin=180 bgcolor=#CCCCCC> <center> <p align=center style="font-szie:9pt; line-height: 100%">正在进入脚本之家,请稍侯……</p> <span id=sb style="width: 500px"> <div style="filter: Alpha(Opacity=0, FinishOpacity=60, style=1, StartX=0, StartY=0, FinishX=100, FinishY=0); width: 0%; height: 12px; position: absolute; background: #9999ff"></div> <div style="font-size: 12px; width: 100%; color: #ff3333; font-family: arial; text-align: center"></DIV> </span> </center> </body> </html>
The code can be run directly by copying and pasting it. You can try it out.
The above is the complete code to implement the page jump progress bar in JS shared with you. I hope it will be helpful to your learning.
