基于属性值在另一个之前插入元素

[英]insert element before another based on attribute value

I create a DIV on the fly and want to position between other Div's it based on their attribute value. 我在飞行中创建了一个DIV,并希望根据其属性值在其他Div之间进行定位。

I would like to have it in sequence. 我希望按顺序进行。

<div data-door="1">1</div>
<div data-door="3">3</div>
<div data-door="4">4</div>
<div data-door="6">6</div>

My code below works but at certain point breaks and the new div starts going out of sequence. 我的代码在下面工作,但在某些时间点,新的div开始不按顺序排列。

example of out of sequence 1 2 2 3 4 5 4 无序的例子1 2 2 3 4 5 4

<input id="txtValue" type="text" > 
<button id="addMe">Add</button>
<div id="container">
    <div data-door="3">3</div>
</div>
$("#addMe").click(function(){
    var strValue = $("#txtValue").val()
    var newDiv = '<div data-door="' + strValue + '">'+ strValue +'</div>'

    //loop thru all divs with data-door
    $('*[data-door]').each(function(){
        console.log($(this).attr("data-door"))
        if ( $(this).attr("data-door") >= strValue ) {

            $(this).prepend(newDiv)
            return false; 
        }
        else{
            $("#container").append(newDiv)
            return false; 
        }

    });

});

I can't figure why is it going of of sequence 我无法理解为什么它会顺序排列

Too complicated: 太复杂:

 $("#addMe").click(function(){ var strValue = $("#txtValue").val(); var str = '<div data-door="' + strValue + '">'+ strValue +'</div>'; var wrapper = $('#container'); $(wrapper).append(str); $('div[data-door]').sort(sortIt).appendTo(wrapper); }); function sortIt(a, b){ return ($(b).data('door')) < ($(a).data('door')) ? 1 : -1; } 
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input id="txtValue" type="text" > <button id="addMe">Add</button> <div id="container"> </div> 

You're returning false in both cases in your loop, causing it to break after the first iteration. 你在循环中的两种情况都返回false,导致它在第一次迭代后中断。 This works: 这有效:

$("#addMe").click(function(){
  var strValue = $("#txtValue").val();
  var str = '<div data-door="' + strValue + '">'+ strValue +'</div>';
  if($.trim($("#container").html())==''){ 
    $('#container').append(str);
  } else {
    //loop thru all divs with data-door
    var added = false;

    $('*[data-door]').each(function(){
      console.log($(this).attr("data-door"))
      if ( $(this).attr("data-door") >= strValue ) {
        $(this).prepend('<div data-door="' + strValue + '">'+ strValue +'</div>')
        added = true;
        return false; 
    }});

    if (!added) {
      $("#container").append(str)
    }
  }
});
