Select and radio form echo functions to avoid using jquery to load assignment

select, radio form echo avoids jquery loading assignment
Notes:

Copy the codeThe code is as follows:

 
<html> 
<body> 
<form method="post" action=""> 
<!-- If the reset function is used in the form, the following code is not recommended -->
<input type="radio" name="visible" value="1" />Show<br>
<input type="radio" name="visible" value="0" />Hide<br>
<select name="orderBy" > 
<option value="0">0</option> 
<option value="1">1</option> 
</select><br> 
<input type="reset"> 
</form> 
</body> 
</html> 

Not recommended: Use the following js code

Copy the codeThe code is as follows:

 
<script type="text/javascript"> 
<!-- 
$(function(){ 
//It is not the default value of the data when echoing
$("input[type=radio][name=visible]").each(function() { 
if ($(this).val() == '${}') { 
$(this).attr("checked", "checked"); 
} 
}); 
$("#orderBy option").each(function() { 
if ($(this).val() == '${}') { 
$(this).attr("selected", "selected"); 
} 
}); 
}); 
//--> 
</script> 

The best way is to make logical judgments on the jsp page

Copy the codeThe code is as follows:

 
<!-- The following code is recommended -->
<input type="radio" name="visible" value="1" <c:if test="${==1}">checked="checked"</c:if>/>Show<br>
<input type="radio" name="visible" value="0" <c:if test="${==0}">checked="checked"</c:if>/>Hide<br>
