jquery radio operation code_jquery

//Set the second one as selected

//if(<%=rows["sex"]%>=="2"){$(':radio[name=sex]' ).eq(1).attr('checked',true);}

//Design value=2 to be in the selected state
//if(<%=rows["sex"] .ToString() %>=='2'){$("input[name='sex']").attr("checked",'2');}


if (<%=rows["sex"]%>=="2"){$("input[name=sex][value=2]").attr("checked",true);}

I did something NB today and none of the above three conditions worked. The reason is that the local database has been operating on the remote database.

JQuery gets radio

Copy code The code is as follows:

<div>
<input id="Radio1" type="radio" name= "rad" value="1" checked />1
<input id="Radio2" type="radio" name="rad" value="2" />2
<input id ="Radio3" type="radio" name="rad" value="3" />3
<input id="Radio4" type="radio" name="rad" value="4" / >4
<input id="Radio5" type="radio" name="rad" value="5" />5
<input id="Button1" type="button" value ="button" onclick="return Button1_onclick()" />
<input id="Button2" type="button" value="button" onclick="return Button2_onclick()" />
</div>

<script language="javascript" type="text/javascript">
// <![CDATA[
function Button1_onclick() {
$("input").each(function () {
if (this.type == 'radio') {
alert($(this).val());
}
});
}
function Button2_onclick() {
//alert($("input[@type=radio]:checked").val());
//alert($ ("input[name='rad']:checked").val());
alert($("input[@type=radio]").val());
}
// ]]>
</script>
