// <!CDATA[
function Text1_onmouseout() {
if (Text1.value== " "){
alert( "不能为空 ");
Text1.focus();
}
}
// ]]> 这是个什么东西？
------解决方案--------------------
建议你写在焦点离开事件 onblur= "return Text1_onmouseout（) "
然后你的函数也有问题
function Text1_onmouseout() {
var Text1=window.document.getElementById( 'Text1 ');
if (Text1.value== " "){
alert( "不能为空 ");
Text1.focus();
return false;
}
return true;
}
------解决方案--------------------
onmouseout= "return Text1_onmouseout() "
这里有问题
还有最好用w3c的标准写javascript
------解决方案--------------------
function Text1_onmouseout() {
if (document.getElementById( "Text1 ").value== " "){
alert( "不能为空 ");
Text1.focus();
return;
}
}
<input id= "Text1 " type= "text " onblur= "return Text1_onmouseout() " /> </div>
