根据条件将文本/内容从TD复制到另一个TD

Question

I would like to copy td to another td by condition.
I do not want use some function on click or press key.. i need function on loading.
For example - Is in td id-'hello' character 1? If yes, move all content to td 'hello_copy'

<td id="hello"> number 1 is good </td>

<td id="hello_copy></td>

RESULT:

<td id="hello"> number 1 is good </td>

<td id="hello_copy>`number 1 is good`</td>

Answer 1

To achieve this you can use the :contains selector to find out if there's a 1 in the text of the #hello cell, and then copy the value to the #hello_copy cell, like this:

 if ($('#hello:contains("1")')) $('#hello_copy').text($('#hello').text()); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table> <tr> <td id="hello">number 1 is good</td> <td id="hello_copy"></td> </tr> </table>
