实现两个INPUT同步输入
不同name时
<script>
function jj(){
var a=document.getElementsByName("s1")[0].value;
document.getElementsByName("s2")[0].value=a;
}
</script>
<input name=s1 type="text" value="corange.cn">
<input name=s2 type="text" value=""οnfοcus="jj()">
请把鼠标移动到第二个文本框
===================
不同IP时候
<script>
function jj(){
var a=document.getElementById("s1").value;
document.getElementById("s2").value=a;
}
</script>
<input id=s1 type="text" value="蓝色理想">
<input id=s2 type="text" value=""οnfοcus="jj()">
请把鼠标焦点放到第二个文本框
====================
实时同步输入
<script language="javascript">
function copyob1toob2(){
document.all["ob_text_2"].value=document.all["ob_text_1"].value
}
</script>
<input type="text" id="ob_text_1" size=20 οnkeyup="copyob1toob2()">
<input type="text" id="ob_text_2" size=20>
=====================
