我实际上面临使用JQUERY Validator进行表单验证的问题。表单即使在字段上有验证错误也会提交。我不确定当字段上存在验证错误时,我们如何禁用或不允许提交表单?我相信当存在验证错误时,bootstrap验证器会禁用该按钮。虽然在我的情况下我使用JQUERY VALIDATOR,所以表单正在提交并调用我正在调用提交的ajax调用。请帮忙!
form id="myform" class="form-horizontal" role="form" action="processAccount" method="post">
<h2><b style="color:#1E90FF;">Account</b></h2>
<div class="form-group">
<label for="Account Number" class="col-sm-3 control-label">Account Number</label>
<div class="col-sm-9">
<input type="text" id="accountNumber" name="accountNumber" placeholder="Account Number" class="form-control" autofocus required />
<!--<span class="help-block">Last Name, First Name, eg.: Smith, Harry</span>-->
</div>
</div>
<div class="form-group">
<label for="Company Number" class="col-sm-3 control-label">Company Number</label>
<div class="col-sm-9">
<input type="number" min="1" id="companyNumber" name="companyNumber" placeholder="Company Number" class="form-control" value=${companyNumber} required />
</div>
</div>
<div class="form-group">
<div class="col-sm-9 col-sm-offset-3">
<!-- <button type="submit" class="btn btn-info btn-block" onclick="doAjaxPost()">Search</button>
-->
<input type="button" style=" font-size: 18px;font-weight: bold; font-family: cursive;" id="processbutton" class="btn btn-info btn-block" value="Load" onclick="doAjaxPost()">
<div id="info" style="color: green; font-weight: bold;" font-size:380%;></div>
<%-- <p ><strong>${message}</strong></p>
--%>
</div>
</div>
</form> <!-- /form -->
<script>
$(document).ready(function () {
$('#myform').validate({ // initialize the plugin
rules: {
accountNumber: {
required: true,
minlength: 7,
maxlength: 7,
digits: true
},
companyNumber: {
required: true,
digits: true
},
submitHandler: function (form) {
console.log("Submitted!");
form.submit();
}
}
});
});
</script>
<script type="text/javascript">
function doAjaxPost() {
// get the form values
var accountNumber = $('#accountNumber').val();
var companyNumber = $('#companyNumber').val();
var token = $("meta[name='_csrf']").attr("content");
var header = $("meta[name='_csrf_header']").attr("content");
var num = 1;
$.ajax({
type: "POST",
url: "./processAccount",
cache: false,
data: "accountNumber=" + accountNumber + "&companyNumber=" + companyNumber,
beforeSend: function(xhr) {
xhr.setRequestHeader(header, token);
},
success: function(response){
// we have the response
$('#info').html(response);
$('#accountNumber').val('');
if(companyNumber!=1)
{
$('#companyNumber').val(num);
}
},
error: function(e){
alert('Error While Request: ' + e);
}
});
}
</script>
在JQUERY Validation块下添加了SubmitHandler方法,但是在请求方法&#39; POST&#39;不支持
submitHandler: function (form) {
console.log("Submitted!");
// get the form values
var accountNumber = $('#accountNumber').val();
var companyNumber = $('#companyNumber').val();
var token = $("meta[name='_csrf']").attr("content");
var header = $("meta[name='_csrf_header']").attr("content");
var num = 1;
$.ajax({
type: "POST",
url: "./processAccount",
dataType: "json",
contentType: 'application/json',
cache: false,
data: "accountNumber=" + accountNumber + "&companyNumber=" + companyNumber,
beforeSend: function(xhr) {
xhr.setRequestHeader(header, token);
},
success: function(response){
// we have the response
$('#info').html(response);
$('#accountNumber').val('');
if(companyNumber!=1)
{
$('#companyNumber').val(num);
}
},
error: function(e){
alert('Error While Request: ' + e);
}
});
form.submit();
}
}
});
});

将提交按钮更改为type="submit"
并删除点击处理程序。
如果您想通过AJAX发送它,您仍然可以在submitHandler
回调中执行此操作。
说明:将点击处理程序设置为doAjaxPost()
,您可能会绕过验证,submitHandler
代码永远不会被执行。
此外,您还有其他错误。 submitHandler
应该是rules
而不是孩子的s !!它不会被称为你使用它的方式。改为使用它:
$('#myform').validate({ // initialize the plugin
submitHandler: function (form) {
console.log("Submitted!");
form.submit(); // default form submitting
},
rules: {
accountNumber: {
required: true,
minlength: 7,
maxlength: 7,
digits: true
},
companyNumber: {
required: true,
digits: true
}
}
});
另请参阅API文档https://jqueryvalidation.org/documentation/
要通过AJAX发送,您应该可以致电doAjaxPost()
而不是form.submit();
- 在这个位置验证已经发生。
submitHandler: function (form) {
console.log("Submitted!");
doAjaxPost(); // custom AJAX call
}

我怀疑除了验证结果之外还调用了doAjaxPost()方法。这个方法里面有什么?
您能否使用(项目页面,文档页面......)识别jquery validate plugin?
答案 2 :(得分:0)
您可以这样做,只需添加以下选项:
$("#myform").validate({
success: function() {
$("button[type='submit']").prop("disabled",false);//enable your submit if success
},
invalidHandler: function(){
$("button[type='submit']").prop("disabled",true); // disable your submit if there is any errors
return false; //Disable post
}
});
