调用以下脚本来动态添加 html 输入元素。下面标记的代码（大约 30 行）有两个问题。
1）应该显示两个输入框，当我在第二个输入框（foox1 - “姓氏”）下方添加标记代码时没有显示。
2) 第二个是我需要 id='suggestions' 是动态的，即链接到 foox1。我应该像使用其余代码一样使用 setAttribute ，但我需要先获得 1) 上面的工作。
<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'> </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++;
}
