Insert Rows to Table using Javascript
Question
I am trying to add rows dynamically in my HTML table and its working fine. Now what I am trying to do is, I want to make them non-editable. That is, once they are created, they should behave as normal <tr> <td> elements! I tried assigning the readonly property after appending but it didn't work.
The HTML
<!DOCTYPE html>
<html>
<head>
<script src = "myScripts.js" type = "text/javascript"></script>
</head>
<body>
<table id="myTable" border="1">
<tr>
<th>First Name</th>
<th>Last Name</th>
</tr>
</table><br>
<button onclick="addRow()">Add Row</button>
</body>
</html>
the Javascript:
var index = 1;
function addRow(){
var table=document.getElementById("myTable");
var row=table.insertRow(table.rows.length);
var cell1=row.insertCell(0);
var t1=document.createElement("input");
t1.id = "txtName"+index;
cell1.appendChild(t1);
var cell2=row.insertCell(1);
var t2=document.createElement("input");
t2.id = "txtAge"+index;
cell2.appendChild(t2);
//t2.readonly = "readonly";
index++;
}

使用setAttribute()方法。
inputElement.setAttribute('readonly',true);

JavaScript is case sensitive.
t2.readOnly = true;

I will recommend the use of jQuery as it drastically reduces the lines of code.
I have used the readOnly attribute as below.
Please see the Demo here
HTML:
<table id="myTable" border="1">
<tr>
<th>First Name</th>
<th>Last Name</th>
</tr>
</table><br><button id="addRow">Add Row</button>
JS:
var i=1;
$('#addRow').click(function(){
var appendString = "<tr><td><input type='text' id='txtName"+i+"' readonly='readonly' /></td><td><input type='text' id='txtAge"+i+"' readonly='readonly' /></td></tr>";
$('#myTable tr:last').after(appendString);
i++;
});
See the code is reduced drastically.
