DHTML代码范例

The following example demonstrates how simulating a click using the click does not, by default, bring the element into focus.

<HTML>
<HEAD>
<SCRIPT>
function simclick1()
{
chk1.focus(); //focus is explicitly set
chk1.click();
}
function simclick2()
{
chk1.click();
}
</SCRIPT>
<SCRIPT FOR=chk1 EVENT=onfocus>
alert("check box is in focus!");
</SCRIPT>
</HEAD>
<BODY>
<P STYLE="font-family:sans-serif;font-weight:bold">DEMO: USING CLICK METHOD
DOES NOT SET FOCUS<P>
<UL STYLE="color:blue;font-family:sans-serif;font-weight:bold">
<LI>Both these buttons apply the click method to the check box. </LI>
<LI>An alert has been set to fire when the check box is put into focus.
</UL>
</PLI>
<INPUT Type="CHECKBOX" id=chk1></INPUT>
<br>
<BUTTON onclick="simclick1()">This button <B>applies the focus method</B> to
check box</BUTTON>
<br><BUTTON onclick="simclick2()">This button <B>does not apply the focus
method</B> to check box</BUTTON>
