settimeout() function
setTimeout, a method of the window object, basically delays the execution of a function or statement until the specified time has passed. The basic syntax of this function is:
setTimeout("expression", delaytime)
"expression" is the function/statement you want delayed, and delaytime is the delay time, in milliseconds.
Example : 1
<script language=javascript>
document.df.hi.value=""
//simply clears the text box
function time(){
setTimeout("document.df.hi.value='Three seconds have gone!'",3000)
}
</script>
<form name="df">
<input type="text" name="hi" size="28">
<input type="button" value="Start" onClick="time()">
</form>
Result:
Example : 2
<script language=javascript>
var c=0
document.go.hi.value=""
function count()
{
document.go.hi.value=c
c=c+1
setTimeout("count()",1000)
}
</script>
<form name="go">
<input type="text" name="hi" size="12">
<input type="button" value="Start" onClick="count()">
</form>
Result:
