Question

我的对象是，

var names =["LET_ABC","PET_DEF","Num_123","Num_456","SET_GHI","RET_JKL"];

现在我必须将包含“Num”的值移到最后，这意味着在“Num”值之后应该没有值。

这是我如何将值添加到数组

 result.each(function () {
        var tempObject = {},
            attributes = $(this).data();
        names.push(attributes.prefix+ '_' + attributes.value)
    });

我可以以某种方式操纵上面的代码，使“Num”值最后移动。

我需要类似的东西，

var names =["LET_ABC","PET_DEF","SET_GHI","RET_JKL","Num_123","Num_456"];

Answer 1

for(var i=0;i<names.length;i++){
  if(names[i].match("^Num")){   
    names.push(names.splice(i, 1)[0]);
  }
}

Answer 2

工作示例（评论中有解释）： -

var names =["LET_ABC","LET_DEF","Num_123","Num_456","LET_GHI","LET_JKL"];//your array

function movetoLast(names,checkword){// function with array and checking prefix

 $(names).each(function(index,value){ // iterate over array
   if(value.indexOf(checkword) >= 0){ // check value have that prefix or not in it
      names.push(names.splice(names.indexOf(value), 1)[0]); // if yes move that value to last in array
   }
 });
 
 return names; // return modified array
}


var names = movetoLast(names,"Num");// call function

console.log(names); // print modified array in console

Answer 3

尝试使用此简单的Array#filter和Array#concat

＆＃13;

var names = ["LET_ABC", "PET_DEF", "Num_123", "Num_456", "SET_GHI", "RET_JKL"];
console.log(names.filter(a => !a.match(/(\d+)/g)).concat(names.filter(a => a.match(/(\d+)/g))))

Answer 4

我会将数字放在一个单独的数组中，以便在最后连接两个数组。

result.each(function () {
            var tempObject = {}, attributes = $(this).data();
            var numsArray = [];        
            if (attributes.prefix==Num){
              numsArray.push(attributes.prefix+ '_' + attributes.value);
            }else{
              names.push(attributes.prefix+ '_' + attributes.value)
            }

            names.concat(numsArray); 
     });

Answer 5

如果数组具有“Num”前缀并使用 unshift 将值添加到数组的开头，请使用 push 将值添加到数组末尾如果它没有“Num”前缀。工作代码：

var names =["LET_ABC","PET_DEF","Num_123","Num_456","SET_GHI","RET_JKL"];

$(document).ready(function(){
    result_array = [];
    $.each(names, function(index, value){
        if (value.substring(0,3)=="Num"){
            result_array.push(value);
        } else{
            result_array.unshift(value);
        };
    });
    console.log(result_array);
});
