JavaScript HTML content manipulation

Why doesn't this code work? innerHTML cannot handle something so complex?

<html>
<head>
    <script type="text/javascript">
        function addTable() {
            var html = "<table><tr><td><label for="name">Name:</label></td><td><input type="text" id="name"></input></td></tr>"; +
                "<tr><td><label for="remarks">Remarks:</label></td><td><input type="text" id="remarks"></input></td></tr></table>";
            document.getElementById("addtable").innerHTML = html;
        }
    </script;


</head>
<body>
    <input type="submit" value="New Table" onClick="addTable()"/>
    <div id="addtable"></div>
</body>
</html>

A simpler example like this one works fine:

var html = "<table><tr><td>123</td><td>456</td></tr></table>";

Answer №1

To prevent issues, make sure to escape double quotes inside the string assigned to the html variable or simply wrap the string in single quotes. Utilize a text editor that highlights syntax and errors to easily identify mistakes like the extra semicolon in your assignment.

Answer №2

Looks like your quoting is not working properly. It seems you have double quotes within the string:

"<tr><td><label for="remarks">Remarks:</label></td><td><input .... 

Make sure to check the Firefox error console first, as errors like that are usually logged there.

Answer №3

Your text is currently formatted with double quotes and also contains them within the text itself. It would be better to switch to using single quotes within the text.

var html = "<table><tr><td><label for='name'>Name:</label></td><td><input type='text' id='name'></input></td></tr>"; +
"<tr><td><label for='remarks'>Remarks:</label></td><td><input type='text' id='remarks'></input></td></tr></table>";

Answer №4

Replace the double quotes with single quotes in the code below:

let html = "<table><tr><td><label for='name'>Name:</label></td><td><input type='text' id='name'></input></td></tr>" + "<tr><td><label for='remarks'>Remarks:</label></td><td><input type='text' id='remarks'></input></td></tr></table>";

Happy coding!!

Answer №5

To insert a string into innerHTML, remember to either escape double quotes or opt for single quotes.

Answer №6

Your string contains a mistake, please use the following corrected code snippet:

var html = "Name:"; + "Remarks:"; document.getElementById("addtable").innerHTML = html;
