jquery - 具有三个语句的 For 循环

Question

这可能吗？1 for 循环 3 语句？

    for(var i =0; i< aObj.length;i++)
(var a =0; a< bObj.length;a++)
(var b =0; b< cObj.length;b++){
         //sOME CODE HERE
    }

Answer 1

不，这是无效的 javascript 语法。根据您的要求，您可以使用 3 个嵌套的 for 循环或使它们连续。

例如：

for(var i = 0; i < aObj.length; i++) {
    for(var a = 0; a < bObj.length; a++) {
        for(var b = 0; b < cObj.length; b++) {
            // some code here
        }
    }
}

或者：

for(var i = 0; i < aObj.length; i++) {
    // some code here
}

for(var a = 0; a < bObj.length; a++) {
    // some code here
}

for(var b = 0; b < cObj.length; b++) {
    // some code here
}

但是，这将再次取决于您需要对这些变量做什么。

我认为tat是不可能的更好的选择：

for(var i =0; i< aObj.length;i++){
  for(var a =0; a< bObj.length;a++){
   for(var b =0; b< cObj.length;b++){
   //sOME CODE HERE
   }
  }
}

Answer 3

this is my actual Code guys..Im getting the last items for Name,Code and Category not per items in array

var CodeObj=new Array(); var NameObj=new Array(); new aObj = new Array();
var CatObj=new Array(); var Codeindex= 0;
var Nameindex= 0; var Catindex= 0; aindex = 0; 


    $(req.responseText).find('Name').each(function(){ 
                             NameObj[Nameindex] = $(this).text();
                             Nameindex +=0;

                         for(var i =0; i< NameObj.length;i++){
                              $(this).append(NameObj[i]+"<br/>");
                           } //1st loop to get the Name

     }) 

    $(req.responseText).find('Code').each(function(){ 
                   CodeObj[Codeindex] = $(this).text();
                    Codeindex +=0;
                  for(var a =0; a< CodeObj.length;a++){
                        $(this).append(CodeObj[a]+"<br/>");

                  } //2nd loop to get the Code

     });


     $(req.responseText).find('Category').each(function(){ 
                          CatObj[Catindex] = $(this).text();
                          Catindex +=0;
                    for(var b =0; b< CatObj.length;b++){
                                $(this).append(CatObj[b]+"<br/>");

                    } //3rd loop to get the category
            });
   //codes to append in list view                            
       var $content = $('<li><a href="#"><img src="../../img/album-bb.jpg"><h3>Name: '+ NameObj[i] + '</h3><p>Code: '+ CodeObj[a] + '</p><p>Category: '+  CatObj[b] + '</p></a><a href="#purchase" data-rel="popup" data-position-to="window" data-transition="pop">Add to favorites</a></li>');                              
      $('#RecipeList').append($content).listview('refresh');
