好的,这就是我想要做的...在创建段落时使用DOM创建删除按钮以及编辑。但删除按钮似乎总是删除第一段而不是删除相应的段落..这是我的代码:
Javascript:
function writePara()
{
var comment = document.getElementById("usrinput").value;
var newParagraph = document.createElement('p');
newParagraph.textContent = comment;
document.getElementById("updateDiv").appendChild(newParagraph);
var button = document.createElement("button");
var Btext=document.createTextNode("EDIT");
button.appendChild(Btext);
document.getElementById("updateDiv").appendChild(button);
button.onclick =
(
function()
{
var edit = prompt("Type to edit", "");
newParagraph.innerHTML = edit;
}
);
var button2 = document.createElement("button");
var Btext2=document.createTextNode("DELETE");
button2.appendChild(Btext2);
document.getElementById("updateDiv").appendChild(button2);
button2.onclick =
(
function ()
{
var items = document.querySelectorAll("#updateDiv p");
if (items.length)
{
var child = items[0];
child.parentNode.removeChild(child);
}
button.parentNode.removeChild(button);
button2.parentNode.removeChild(button2);
}
);
addBr();
}
HTML:
<body onload="radio()">
<div id="paraButton" align="left">
<form><h3>Enter your Paragraph content here:</h3>
<textarea cols="20" rows="10" id="usrinput">Enter your texts here...</textarea>
</form>
<form id="one"><input type="button" value="Apply" onclick="writePara()"/></form>
<div id="updateDiv" name ="update"><h1>Space for Paragraph</h1> </div>
</div>
<div id="radioButton">
<h3>Type your radio button here:</h3>
<input type="text" name="option" id="option" value="Example 1" />
</br></br>
<button id="AddButton">Add</button>
<button id="RemoveButton">Remove</button>
</br></br></br></br></br></br></br></br>
<div id="updateDivRadio"><h1>Space for Radio Button</h1></div>
</div>
</body>
P.S:radio()
函数工作正常,这只是我遇到问题的一段。
答案 0 :(得分:0)
好的,我得到了其他人的帮助,所以决定在这里分享......
将button2.onclick
更改为此作品。
button2.onclick =
(
function ()
{
newParagraph.parentNode.removeChild(newParagraph);
button.parentNode.removeChild(button);
button2.parentNode.removeChild(button2);
}
);
