HomeWeb Front-endJS TutorialImplement global validation under bootstrapValidator based on jQuery_jquery

BootstrapValidator is a form inspection jQuery plug-in specifically for Boostrap v3. It can implement many commonly used inspection functions, is easy to expand, and also supports Chinese! It can be used out of the box for bootstrap users.

Prefix:

Introducing jQuery, bootstrap, bootstrapValidator

Problem description:

The project requires that the & symbol cannot be entered in all form input boxes. I didn’t find any method available in bootstrap, so I had to do it myself

Thinking:

Use regular expressions.

There are two situations. The first one is that if the input box has its own regular verification, you don’t need to worry about it (generally speaking, regular verification is used to strictly control the input); the second one is that if there is no regular expression, you need to add that you cannot input. &'s regular rule.

It is necessary to overload the bootstrapValidator initialization function and correct the initialization settings according to the above two situations. Finally, restore the original bootstrapValidator function (this step is necessary, the original bootstrapValidator function has a lot of associated stuff of its own, which cannot be lost);

Implementation:

/*add chenhua 2015.10.16 重写bootstrapValidator方法?给每一个验证项都添加禁止输入"&"符号*/ 
$(function(){  //保存原始的bootstrapValidator 
  var overwrite = $.fn.bootstrapValidator;   //重载bootstrapValidator
  $.fn.bootstrapValidator = function(options){ 
    //恢复原来的bootstrapValidator,因为其加了很多数据是不能丢失的 
    $.fn.bootstrapValidator = overwrite; 
            //这里有两种做法,第一种是直接修改arguments内容,使其包含不能输入&的验证,然后调用即可;    //第二种是先使用arguments来初始化,然后使用调用bootstrapValidator的函数来给非正则表达式验证的项添加不能输入&的验证    //这里我们使用了第二中。  
    var validtor = overwrite.apply(this,arguments); 
    if($.type(arguments[0]) == "object"){ 
      var vtor = this.data("bootstrapValidator"),      //过滤出输入框表单项   
      fileds = this.find("input[name][type='hidden'],input[name][type='password'],input[name][type='text'],textarea[name]").not(":disabled,[type='hidden']"); 
      fileds.each(function(){ 
        //本身没有正则验证才添加不能输入&的验证 
        if(!vtor.getOptions($(this).attr('name'),'regexp','regexp')){ 
         vtor.addField($(this).attr('name'), 
            { 
              validators: { 
                regexp: { 
                  regexp: /^[^&]*$/, 
                  message: "不能包含&字符" 
                } 
              } 
          }) 
        } 
      }) 
    } 
    return validtor; 
  } 
})

Javascript Data Types : Is there any difference between Browser and NodeJs?Javascript Data Types : Is there any difference between Browser and NodeJs?May 14, 2025 am 12:15 AM

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

Python vs. JavaScript: A Comparative Analysis for DevelopersPython vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.
