我有一个表单,我正在使用jQuery验证插件进行验证。我想添加一个条件选择框(根据另一个选择填充/显示的选择框)并让它也进行验证。以下是我到目前为止的情况:
$(document).ready(function(){
$("#customer_information").validate({
//disable the submit button after it is clicked to prevent multiple submissions
submitHandler: function(form){
if(!this.wasSent){
this.wasSent = true;
$(':submit', form).val('Please wait...')
.attr('disabled', 'disabled')
.addClass('disabled');
form.submit();
} else {
return false;
}
},
//Customizes error placement
errorPlacement: function(error, element) {
error.insertAfter(element)
error.wrap("<div class=\"form_error\">")
}
});
$(".courses").hide();
$("#course_select").change(function() {
switch($(this).val()){
case "Certificates":
$(".courses").hide().parent().find("#Certificates").show();
$(".filler").hide();
break;
case "Associates":
$(".courses").hide().parent().find("#Associates").show();
$(".filler").hide();
break;
case "":
$(".filler").show();
$(".courses").hide();
}
});
});
HTML:
<select id="course_select">
<option value="">Please Select</option>
<option value="Certificates">Certificates</option>
<option value="Associates">Associates</option>
</select>
<div id="Form0" class="filler"><select name="filler_select"><option value="">Please Select Course Type</option></select></div>
<div id="Associates" class="courses">
<select name="lead_source_id" id="Requested Program" class="required">
<option value="">Please Select</option>
<option value="01">Health Information Technology</option>
<option value="02">Human Resources </option>
<option value="03">Marketing </option>
</select>
</div>
<div id="Certificates" class="courses">
<select name="lead_source_id" id="Requested Program" class="required">
<option value="">Please Select</option>
<option value="04">Accounting Services</option>
<option value="05">Bookkeeping</option>
<option value="06">Child Day Care</option>
</select>
</div>
到目前为止,select正在为我工作,但验证认为即使选择了值,该字段也是空的。
看起来有很多方法可以在jQuery中进行条件选择。这是我设法解决的最好方式(我是jQuery的新手),但我很想听听你们认为“最好”的方式,特别是如果它与验证插件配合得很好。谢谢!

需要进行两项更改:
1)两个子选择框都分配了相同的名称属性,分配不同的名称 每个选择框的属性(这将用于分配验证规则):
<div id="Associates" class="courses">
<select name="lead_source_id_1" id="Requested Program" class="required">
<option value="">Please Select</option>
<option value="01">Health Information Technology</option>
<option value="02">Human Resources </option>
<option value="03">Marketing </option>
</select>
</div>
<div id="Certificates" class="courses">
<select name="lead_source_id_2" id="Select1" class="required">
<option value="">Please Select</option>
<option value="04">Accounting Services</option>
<option value="05">Bookkeeping</option>
<option value="06">Child Day Care</option>
</select>
</div>
<input type="hidden" name="lead_source_id" id="lead_source_id" value="" />
2)为validate方法选项中的每个子选择框添加所需的依赖关系规则,如下所示:
$(document).ready(function(){
$("#customer_information").validate({
rules:{
lead_source_id_1: {
required: function(element){
var retVal = ($("#course_select").val() == "Associates");
return retVal;
}
},
lead_source_id_2: {
required: function(element){
var retVal = ($("#course_select").val() == "Certificates");
return retVal;
}
}
},
//disable the submit button after it is clicked to prevent multiple submissions
submitHandler: function(form){
if(!this.wasSent){
this.wasSent = true;
$(':submit', form).val('Please wait...')
.attr('disabled', 'disabled')
.addClass('disabled');
form.submit();
//return false;
} else {
return false;
}
},
//Customizes error placement
errorPlacement: function(error, element) {
error.insertAfter(element)
error.wrap("<div class=\"form_error\">")
}
});
$(".courses").hide();
$("#course_select").change(function () {
switch ($(this).val()) {
case "Certificates":
$(".courses").hide().parent().find("#Certificates").show();
$(".filler").hide();
break;
case "Associates":
$(".courses").hide().parent().find("#Associates").show();
$(".filler").hide();
break;
case "":
$(".filler").show();
$(".courses").hide();
}
});
$(".courses select").change(function () {
$("#lead_source_id").val($(this).val());
});
});
