您好我有HTML表单,我正在尝试在按钮单击事件上创建表单的div部分。我有像下面的javascript的HTML代码,但它没有在按钮单击事件后添加表单元素。我需要在Person div元素中创建所有行和单元格以及输入文本框,并在单击AddPerson按钮时附加或添加Div-Person。我有一些Div元素包含其他输入元素,我需要在点击与Div标签关联的按钮后添加或创建。下面是One Div元素的示例代码,包含3个输入字段和一个按钮。非常感谢帮助.i或j变量的值必须递增。它总是采取i = 1这是一个问题吗?

我修改了javascript函数,它还在页面顶部创建了2个名字和姓氏文本框,但是一旦代码从java脚本结束,那些文本框就会消失。
var i=2;
var j=2;
function CreatePerson(divName)
{
var Y= document.createElement("div");
Y.id=divName+i;
// Y.innerHTML="<tr>
var appendText="<tr><td>First Name</td><td align="+"left"+"><input name="+"Key_FirstName_"+i+" size="+"35"+" type="+"text"+" /></td></tr><tr><td>Last Name</td></tr><tr><td align="+"left"+"><input name="+"Key_lastName_"+i+" size="+"35"+" type="+"text"+" /></td></tr>";
Y.innerHTML=appendText;
document.getElementById(divName).after(Y);
i++;
}
答案 0 :(得分:-1)
试试这个
<form method="POST">
<div id="dynamicInput">
Entry 1<br><input type="text" name="myInputs[]">
</div>
<input type="button" value="Add another text input" onClick="addInput('dynamicInput');">
</form>
var counter = 1;
var limit = 3;
function addInput(divName){
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "Entry " + (counter + 1) + " <br><input type='text' name='myInputs[]'>";
document.getElementById(divName).appendChild(newdiv);
counter++;
}
}
