test.htm:
<head>
<title> JUST A TEST </title>
<script language= "javascript ">
function testJs(){
alert(document.form1.name1.value);
if(document.form1.name1.value== " "){
alert( "ttt ");
return false;
}
if(document.form1.name1.value== "jack "){
alert( "ggg ");
return true;
}
}
function tt(){
alert(form1.name1.value);
return false;
}
</script>
</head>
<body>
<form name= "form1 " action= "tt.html " >
<input type= "text " name= "name1 " />
<input type= "submit " onclick= "testJs(); " />
</form>
</body>
</html>
用onclick调用testJs()时,判断语句都执行了,但是无论name1的value为null还是jack
都转到了tt.html页面.
不知道是那里出了问题,谢谢高手指点!!!!
------解决方案--------------------
根本不需要再用onclick()了.你已经是submit按钮了.直接写:
<form name= "form1 " action= "tt.html " onsubmit= "return testJs(); ">
就OK了.
