问题描述
我有一个带有两个输入文本框的表单,我已经包括了两个jQuery验证规则:
< script src =../../ Scripts / jquery-validate / jquery.validate.jstype =text / javascript>< / script>
< script type =text / javascript>
$(document).ready(function(){
$('#respondForm')。validate({onclick:false,
onkeyup:false,
onfocusout:
highlight:function(element,errorClass){
$(element).css({backgroundColor:'Red'});
},
errorLabelContainer: ,$('div.error-container')),
wrapper:'li',
rules:{
'text':{
required:true,
minlength:5,
maxlength:10
},
integer:{
必需:true,
范围:[0,90]
} b $ b},
消息:{
'text':{
必需:xxx_Required,
minlength:XXX应大于5,
maxlength:XXX不能大于10
},
整数:{
必需:必需,
范围:超出范围:[0,90 ]
}
}
});
});
< / script>
< / head>
。
。
。
< input type =textid =textname =text/>
< br />
< input type =textid =integername =integer/>
< br />
< input type =submitname =submitvalue =Submit/>
< br />
我使用了:
function(element,errorClass){
$(element).css({backgroundColor:'Red'});
}
以突出显示错误控制。现在的问题是,在下面的场景中,两个输入文本框都保持高亮显示(背景颜色:红色):
- 在文本框中输入5个字符1
- 输入文本框2空白
- 现在输入文本框1中有6个字符的文本(有效输入)
- 离开
- 两个文本框的背景颜色保持为红色。其中期望的是文本框1的背景颜色不应为红色
如何解决此问题?
解决方案
找到答案,你必须提供一个 unhighlight
/ p>
将错误类别添加到无效元素及其标签
$(。selector)。validate({
highlight:function(element,errorClass){
$(element).addClass(errorClass);
(element.form).find(label [for =+ element.id +])
.addClass(errorClass);
},
unhighlight:function ){
$(element).removeClass(errorClass);
$(element.form).find(label [for =+ element.id +])
.removeClass (errorClass);
}
});
I have a form with two input textboxes, and I have included jQuery validation rules for both:
<script src="../../Scripts/jquery-validate/jquery.validate.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#respondForm').validate({ onclick: false,
onkeyup: false,
onfocusout: false,
highlight: function(element, errorClass) {
$(element).css({ backgroundColor: 'Red' });
},
errorLabelContainer: $("ul", $('div.error-container')),
wrapper: 'li',
rules: {
'text': {
required: true,
minlength: 5,
maxlength: 10
},
integer: {
required: true,
range: [0, 90]
}
},
messages: {
'text': {
required: "xxx_Required",
minlength: "XXX Should be greater than 5",
maxlength: "XXX Cannot be greater than 10"
},
integer: {
required: "is required",
range: "is out of range: [0,90]"
}
}
});
});
</script>
</head>
.
.
.
<input type="text" id="text" name="text" />
<br />
<input type="text" id="integer" name="integer" />
<br />
<input type="submit" name="submit" value="Submit" />
<br />
I have used:
function(element, errorClass) {
$(element).css({ backgroundColor: 'Red' });
}
to highlight the error control. Now the problem is that in the following scenario, both the input textboxes remain highlighted (background color: red):
- Input text with less than 5 characters in text box 1
- Leave text box 2 blank
- Hit submit
- Both input text box background will be changed to red (which is correct)
- Now enter a text which has 6 characters in text box 1 (valid input)
- Leave text box 2 empty
- Hit submit
- The background color for both the textboxes remains red. Where as the expectation is that the background color of text box 1 should not be red
How do I resolve this problem?
解决方案
Found the answer, you have to provide an unhighlight
property as well.
Adds the error class to both the invalid element and its label
$(".selector").validate({
highlight: function(element, errorClass) {
$(element).addClass(errorClass);
$(element.form).find("label[for=" + element.id + "]")
.addClass(errorClass);
},
unhighlight: function(element, errorClass) {
$(element).removeClass(errorClass);
$(element.form).find("label[for=" + element.id + "]")
.removeClass(errorClass);
}
});
