[英]Validating a Group of Checkboxes using the jQuery validation plugin
使用jquery验证插件时,如何验证一组复选框?
下面是我用于text
的代码,但是如何对一组复选框进行操作?
<form id="newItem" action="formProcess.php" method="post">
<input type="text" class="itemTitle" name="itemTitle" value="" autocomplete="off"><br>
<label for="itemTitle" generated="true" class="error itemTitle" style=""></label><br>
<input type="checkbox" name="country[]" value="US" class="destinations"><br>
<input type="checkbox" name="country[]" value="GB" class="destinations"><br>
<input type="checkbox" name="country[]" value="CA" class="destinations"><br>
<input type="checkbox" name="country[]" value="SE" class="destinations"><br>
<label for="destinations" generated="true" class="error destinations" style=""></label><br>
<input type="submit" name="Submit" value="Submit">
</form>;
$("#newItem").validate({
rules: {
itemTitle: {
required: true,
minlength: 3,
maxlength: 60
},
// How is it done for a group of check boxes?
// I'd like at least 1 destination to be selected, and a maximum of 3. This cannot be left blank.
messages: {
itemTitle: {
required: "Please enter a valid name",
minlength: "Minimum length required is 3 characters",
maxlength: "Maximum length allowed 51 characters"
},
},
submitHandler: function() {
// Other code follows
尝试这个
$("#newItem").validate({
rules: {
"country[]": {
required: true,
minlength: 1,
maxlength: 3
}
},
messages: {
"country[]": {
required: "Check atleast 1",
minlength: "Min 1",
maxlength: "Max only 3"
}
}
});
