<head>
<script type="text/javascript">
function test(){
if(document.form.choice.value='pc'){
window.open('pc.php','_self');
return true;
}
else if(document.form.choice.value='ps2'){
window.open('ps2.php','_self');
return true;
}
else if(document.form.choice.value='ps3'){
window.open('ps3.php','_self');

window.open('psp.php','_self');
return true;
}
}
</script>

<form name="form">ALL
<input type="radio" onClick="test()" name="choice" value="pc">PC
<input type="radio" onClick="test()" name="choice" value="ps2">PS2
<input type="radio" onClick="test()" name="choice" value="ps3">PS3
<input type="radio" onClick="test()" name="choice" value="psp">PSP
</form>
</body>
Also i want to know that how to display the field automatically just by selecting the selected field in Drop down list without 'submit'
另外我想知道如何在没有“提交”的情况下通过在下拉列表中选择选定的字段来自动显示该字段
<select name="genre">
<option value="">--Select Genre and Click Go--</option>
<option value="All">All</option>
<option value="Action / Mission">Action / Mission</option>
<option value="Arcade">Arcade</option>
<option value="Racing">Racing</option>
<option value="Sports">Sports</option>
<option value="Kids">Kids</option>
<option value="Strategy">Strategy</option>
<option value="Adventure">Adventure</option>
</select>

You can get the value of the option by adding onchangeevent in the <select>tag.
您可以通过onchange在<select>标签中添加事件来获取选项的值。
<select name="genre" onchange="selectOption()">
<option value="">--Select Genre and Click Go--</option>
<option value="All">All</option>
<option value="Action / Mission">Action / Mission</option>
<option value="Arcade">Arcade</option>
<option value="Racing">Racing</option>
<option value="Sports">Sports</option>
<option value="Kids">Kids</option>
<option value="Strategy">Strategy</option>
<option value="Adventure">Adventure</option>
</select>
In your script add this
在你的脚本中添加这个
function selectOption(){
//each option value
var option=document.form.genre.value;
alert(option);
}
For redirecting you can use window.locationin your test()method
use this window.location=yourpage.phpinstead of this window.open('pc.php','_self')
对于重定向，您可以window.location在您的test()方法中使用 thiswindow.location=yourpage.php而不是 thiswindow.open('pc.php','_self')
