A brief discussion on bootstrap form validation plug-in BootstrapValidator

This article recommends a Bootstrap Validator made by twitter. Bootstrap itself is made by twitter, so using the original validator will be more trustworthy. Searching for BootstrapValidator on Baidu will show up many models, but I only recommend this one (suddenly I feel a bit "cool [Steve Curry]").

1. Take a quick look

2. Resource reference
After downloading the resource package, you can see the following directory.

Then introduce the following three files into your project.

<link type="text/css" rel="stylesheet" href="${ctx}/components/validate/css/bootstrapValidator.css" />
<script type="text/javascript" src="${ctx}/components/validate/js/bootstrapValidator.js"></script>
<script type="text/javascript" src="${ctx}/components/validate/js/language/zh_CN.js"></script>

• 3. Member name is not empty project configuration

  <form class="form-signin required-validate" action="${ctx}/login" method="post" οnsubmit="return validateCallback(this)">
  	<div class="form-group">
  		<div class="row">
  			<label>账户</label>
  			<input class="form-control" type="text" autofocus name="username" placeholder="请输入会员编号" autocomplete="off"
  				data-bv-notempty />
  		</div>
  	</div>
  </form>

  Copy after login

• data-bv-notempty means that the member number needs to be empty check.
  The p of form-group is required, otherwise a
“too much recursion”
• error will be reported.

• 4. After the page is loaded, enable bootstrap validator

  $(function() {
  	// validate form
  	$("form.required-validate").each(function() {
  		var $form = $(this);
  		$form.bootstrapValidator();
  		
  		// 修复bootstrap validator重复向服务端提交bug
  		$form.on('success.form.bv', function(e) {
  			// Prevent form submission
  			e.preventDefault();
  		});
  		
  		
  	});
  });

  Copy after login

• Add 'class="required-validate" to the form ”' attribute, and then obtain the corresponding form form through jquery, and perform the default bootstrapValidator loading on it.

Be sure to pay attention to the commented part of the code above. For detailed introduction, please refer to Fixing Bootstrap Validator Repeat Submission Bug.

• 5. Verification items when the form form is submitted

function validateCallback(form, callback, confirmMsg) {
	YUNM.debug("进入到form表单验证和提交");

	var $form = $(form);

	var data = $form.data('bootstrapValidator');
	if (data) {
	// 修复记忆的组件不验证
		data.validate();
		
		if (!data.isValid()) {
			return false;
		}
	}

	
	$.ajax({
		type : form.method || 'POST',
		url : $form.attr("action"),
		data : $form.serializeArray(),
		dataType : "json",
		cache : false,
		success : callback || YUNM.ajaxDone,
		error : YUNM.ajaxError	});

	return false;}

Copy after login

• After obtaining the form form in validateCallback, the form verification can be returned through the isValid method Pass or not.

After the form verification passes, the form is submitted to the server through ajax.
