Set a javascript code as a variable

I get a variable from the controller that is a java script code and want to init a variable of java script file with this data as a string.

What I mean is:

Model.TrialScript is equal to the string of:

<script type="text/javascript">var j = new Date();</script>

(I got it from the DB)

and then, I want to do the next thing in my js file:

var TrialScript = '<%= Model.TrialScript %>';

The problem is that TrialScript is not like I expect:

var TrialScript = '<script type="text/javascript">var j = new Date();

assuming I must get the js code as: <script type="text/javascript"> and not: <script type=\"text/javascript\">, how can I solve this issue?

Another thing may helps: I want to run this script only when the user press a button (is called: button1)

Maybe is there an option to call this script from the js after the button is clicked without saving this script as a variable?

any help appreciated!

You can try that way:

var TrialScript = '<%= Model.TrialScript %>';
//remove script tags, get only the code
TrialScript = TrialScript.replace(new RegExp("^<script.*?>(.*)</script>"), "$1");
// transform the code as a JS function
TrialScript = new Function(TrialScript);
// associate to the button1
document.getElementById("button1").onclick = TrialScript;
