Question

以下<div>部分我在重复，在JavaScript函数下面，我想一次又一次地使用。如果可能，请分享您的想法。

 <?php  $new_material = ["a","b","c"];   //array to pass in foreach 

           foreach ($new_material as $mat) {

     ?>

    <div class="row " id="row2">
              <div class="row " id="row2.1">
                <div class="col-xs-2"> 
                  <label>Material Name</label>
                </div>
                <div class="col-xs-3">
                  <label>Brand</label>
                </div>
                <div class="col-xs-2">

        <?php 
          }
          ?>

JavaScript代码：这是JavaScript函数，我想在我复制上面的代码时使用，因为我在foreach()循环中传递了材质名称，因此它基于每个材质名称进行复制。 / p>

function duplicate() {
  document.getElementById('delete_btn').style.visibility = "visible";
  var original = document.getElementById('duplicater');
  var clone = original.cloneNode(true); // "deep" clone
    clone.id = "duplicetor" + ++i; // there can only be one element with an ID
    original.parentNode.appendChild(clone);
   document.getElementById('delete_btn').style.visibility = "hidden";
   document.getElementById('specification').value="";
   document.getElementById('quantity').value="";
   document.getElementById('unit').value="";
}

function removeduplicate(element){
    element=element.parentNode.parentNode;//gets the id of the parent
    element.parentNode.removeChild(element);
}

Answer 1

javascript文件/代码加载的自然位置在头部，所以只需将它放在那里。因为你不希望你的头部被复制（无效的html）。

使用javascript函数而不重复它
