使用JavaScript添加带有动态元素问题的HTML div

[英]using javascript to add html div with dynamic elements issues

调用以下脚本可以动态添加html输入元素。 下面的标记代码(大约30行)有两个问题。

1)当我在第二个输入框(foox1-“ last name”)下方添加标记的代码时,应显示两个输入框(foox1-“ last name”)。

2)第二个是我需要id ='uggestions'来动态化,即链接到foox1。 我应该像其余代码一样使用setAttribute,但是我需要首先获得1)的帮助。

<script language="javascript">

var x = 1;

function add() {
var fooId = "foo";

for (i=1; i<=2; i++)
  {
    //Create an input type dynamically.
    var element = document.createElement("input");

    //Assign different attributes to the element.
    element.setAttribute("type", fooId+x+i);
    element.setAttribute("name", fooId+x+i);
    element.setAttribute("id", fooId+x+i);

    if(i==1){
           element.setAttribute("value", "First name");
           element.setAttribute("onkeyup", "lookup(this.value);");
           element.setAttribute("onblur", "fill();");

     }
    if(i==2){
          element.setAttribute("value", "Last name");

    }
    var foo = document.getElementById("fooBar");
    foo.appendChild(element);

    /************************************************
    This is where the problem is, in this if statement.  
    This part of the code is required for an autofil in the text box

    ************************************************/

    if(i==1){
        foo.appendChild("<div class='suggestionsBox' id='suggestions' style='display: 
            none;'><img src='upArrow.png' style='position: relative; top: -12px; left: 30px;'         
            alt='upArrow' /><div class='suggestionList' id='autoSuggestionsList'>&nbsp;       </div>    </div>");
    }

    /********************************
    end of code with issues
    ******************************/

    var space = document.createTextNode(" ");
    foo.appendChild(space);  

}
        i++;            
            var element = document.createElement("input");
    element.setAttribute("type", "button");
    element.setAttribute("value", "Remove");
    element.setAttribute("id", fooId+x+i);
    element.setAttribute("name", fooId+x+i);    
    element.setAttribute("onclick", "removeRow(this)");
    foo.appendChild(element);

    var br = document.createElement("br");
    foo.appendChild(br);

    x++;

}
</SCRIPT>

您不能在以下上下文中使用.appendChild .appendChild添加节点而不是字符串。

foo.appendChild("<div class='suggestionsBox' id='suggestions' style='display: 
            none;'><img src='upArrow.png' style='position: relative; top: -12px; left: 30px;'         
            alt='upArrow' /><div class='suggestionList' id='autoSuggestionsList'>&nbsp;       </div>    </div>");

它一定要是

foo.innerHTML += "<div class='suggestionsBox' id='suggestions' style='display: none;'><img src='upArrow.png' style='position: relative; top: -12px; left: 30px;' alt='upArrow' /><div class='suggestionList' id='autoSuggestionsList'>&nbsp;  </div>   </div>";

工作演示

编辑:对于您的问题的第二部分,您可以在上述语句中执行id='suggestions_for_' + fooId + x + i (它将产生类似id='suggestions_for_foo11' 。)

您需要在前两行中以" +结尾
