The example in this article describes how to insert the value of the text box into the specified position using JavaScript. Share it with everyone for your reference. The details are as follows:
JavaScript is implemented here to insert the value of the text box into the current specified position. This may have been used in some form submission occasions. This code segment writes the value of the text box into the body area of the current page. If If you have other text boxes set up, you can assign values to these text boxes, which can save users using the form the trouble of inputting.
The operation effect is as shown below:
The specific code is as follows:

<title>插入节点</title>
<script language="javascript">
<!--
function crNode(str)
{
var newP=document.createElement("p");
var newTxt=document.createTextNode(str);
newP.appendChild(newTxt);
return newP;
}
function insetNode(nodeId,str)
{
var node=document.getElementById(nodeId);
var newNode=crNode(str);
if(node.parentNode)//判断是否拥有父节点
node.parentNode.insertBefore(newNode,node);
}
-->
</script>
</head>
<body>
<h2 id="h">在上面插入节点</h2>
<form id="frm" name="frm">
输入文本：<input type="text" name="txt" />
<input type="button" value="前插入" onclick="insetNode('h',document.frm.txt.value);" />
</form>
</body>
