<script type="text/javascript">
//<![CDATA[
function fstatus() {
for (var i=0; i<100000; i++) {
window.status = "now process is /"" +i+ "/"";
}
}
function finnerHtml() {
for (var i=0; i<1000; i++) {
document.getElementById("demo").innerHTML = "now process is /"" +i+ "/"";
}
}
//]]>
</script>
<input type="button" onclick="fstatus()" value="test status"/>
<input type="button" onclick="finnerHtml()" value="test innerHTML"/>
<div id="demo"></div>
In the above example,one have a loop and display it real time use innerHTML property, another is use window.status.
However, the window.status in real time that perfect display the loop digit, but the innerHTML property is not.
Just display result digit: now process is "999".
And how to using innerHTML display real time data? can but use window.setTimeout, or window.setInterval method, like this:
var cnt=0;
function finnerHtml() {
if (cnt++>=1000) return;
document.getElementById("demo").innerText = "now process is /"" +cnt+ "/"";
window.setTimeout(finnerHtml,10)
}
But, it's no convenient. the display speed is not well, and we must control something.
e.g.
setTimeout variables, when it completely.
So, I propose winodw.status to replace innerHTML property when display in real time.
