Prepending a first row to table with jQuery

Question

I have a table in my code:

<table class="mainTable">
</table>

I want to prepend a head row to it.

var filter_all_head_row="
            <tr>\
                <th>smth</th>\
                                ...
                    <th>smth</th>\
                        </tr>
";

I'm trying to do it in onload of my page with this code:

$("table.mainTable").prepend(filter_all_head_row);

By the console says:

Uncaught SyntaxError: Unexpected token ILLEGAL

Solutions?

Answer 1

You are missing at least two \ in your string literal:

var filter_all_head_row="
    <tr>\
        <th>smth</th>\
        <th>smth</th>\
    </tr>
";

Should be:

var filter_all_head_row = "\
  <tr>\
    <th>smth</th>\
    <th>smth</th>\
  </tr>\
";
