Use .is(':checked')instead: Working jsFiddle
使用.is(':checked')来代替：工作的jsfiddle
var eu_want_team = $('#eu_want_team').is(':checked');
alert(eu_want_team);
or as @Itay said in comments you can use jQuery's .prop()to get the checked property value:
或者正如@Itay 在评论中所说，您可以使用 jQuery.prop()来获取已检查的属性值：
alert($("#eu_want_team").prop("checked"));

This will work :
这将工作：
if ($('#element').is(":checked")) {
eu_want_team = 1;
} else {
eu_want_team = 0;
}
alert(eu_want_team);
