脚本中的必需项不起作用
$("#s_postby").attr('required', false); // put the id of the input field that you whant required
$("#s_postby").attr('required', true); // put the id of the input field that you whant required
我在项目帖子上的osclass主题中制作了一些无线电字段！
<div id="postby" class="property-ads-100">
<label>
<span class="required_fields">*</span>
<?php _e('Posted By', 'ctg_housing'); ?>
</label>
<div class="item-post-postby-checkbox columns-0">
<input type="radio" name="s_postby" value="owner" id="s_postby0" <?php if(isset($housing['s_postby']) && $housing['s_postby'] =='owner') { echo 'checked="checked"'; }; ?>>
<label for="s_postby0">
<?php _e('Owner', 'ctg_housing'); ?>
</label>
</div>
<div class="item-post-postby-checkbox columns-0">
<input type="radio" name="s_postby" value="agent" id="s_postby1" <?php if(isset($housing['s_postby']) && $housing['s_postby'] =='agent') { echo 'checked="checked"'; }; ?>>
<label for="s_postby1">
<?php _e('Agent', 'ctg_housing'); ?>
</label>
</div>
<div class="item-post-postby-checkbox columns-0">
<input type="radio" name="s_postby" value="broker" id="s_postby2" <?php if(isset($housing['s_postby']) && $housing['s_postby'] =='broker') { echo 'checked="checked"'; }; ?>>
<label for="s_postby2">
<?php _e('Broker', 'ctg_housing'); ?>
</label>
</div>
<div class="item-post-postby-checkbox columns-0">
<input type="radio" name="s_postby" value="agency" id="s_postby3" <?php if(isset($housing['s_postby']) && $housing['s_postby'] =='agency') { echo 'checked="checked"'; }; ?>>
<label for="s_postby3">
<?php _e('Agency', 'ctg_housing'); ?>
</label>
</div>
</div>
我将其隐藏在某些类别上（脚本中的必需项不起作用!!）为什么??
<script type="text/javascript">
$('#catId').change(function(){
if( $('#catId').val() == "28" || $('#catId').val() == "29" ||
$('#catId').val() == "30" || $('#catId').val() == "31")
{
$("#postby").hide(); // change Posted By with ID you give to the div
$("#s_postby").attr('required', false); // put the id of the input field that you whant required
}else
{
$("#postby").show(); // change Posted By with ID you give to the div
$("#s_postby").attr('required', true); // put the id of the input field that you whant required
}
});
</script>
我现在需要的是在显示时需要这个无线电字段，而不是要求隐藏！当show和required我需要一条错误消息Posted by：这个字段是必需的！
希望有人可以帮助我！
