Detailed explanation of examples of jQuery Validate verifying multiple names

This article mainly introduces the method of jQuery Validate to verify multiple identical names. Friends who need it can refer to it

Introduction:

There is the following code in the form page

 <form>
  <input name="zhai"/><!-- 三个相同name的input -->
  <input name="zhai"/>
  <input name="zhai"/>
 </form>

jquery validate only verifies the first input box when validating multiple same names.

Solution 1:

Add the following code to the js corresponding to the form page. Only the current page can solve the verification of multiple names

 if ($.validator) {
   $.validator.prototype.elements = function () {
    var validator = this,
     rulesCache = {};
    return $(this.currentForm)
    .find("input, select, textarea")
    .not(":submit, :reset, :image, [disabled]")
    .not(this.settings.ignore)
    .filter(function () {
     if (!this.name && validator.settings.debug && window.console) {
      console.error("%o has no name assigned", this);
     }
     rulesCache[this.name] = true;
     return true;
    });
   }
  }

Solution 2:

Modify the source file and all pages can verify multiple names

1: Modify the jquery.validate.js file

Use ctrl+F to find this.name in rulesCache CommentRemove the following code.

elements: function() {
   var validator = this,
    rulesCache = {};
   // select all valid inputs inside the form (no submit or reset buttons)
   return $(this.currentForm)
   .find("input, select, textarea")
   .not(":submit, :reset, :image, [disabled]")
   .not( this.settings.ignore )
   .filter(function() {
    if ( !this.name && validator.settings.debug && window.console ) {
     console.error( "%o has no name assigned", this);
    }
    // 注释掉这里
    // select only the first element for each name, and only those with rules specified
    //if ( this.name in rulesCache || !validator.objectLength($(this).rules()) ) {
    // return false;
    //} 
    rulesCache[this.name] = true;
    return true;
   });
  },

Method 2: Modify the jquery.validate.min.js file

Use ctrl+F to find (c[this.name]= !0,!0)})

 return !this.name && b.settings.debug && window.console && console.error("%o has no name assigned", this),
//this.name in c || !b.objectLength(a(this).rules()) ? !1 : (c[this.name] = !0, !0)//注释这行
c[this.name] = !0, !0 //添加这行
