<#assign x=true>
}
else{
<#assign x=false>
}

however I am not able to get value of x. Can someone please let me know how to assign freemarker variable inside javascript.

Answer 1

This cannot be done. Javascript is evaluated in the browser and FreeMerker is evaluated on the server before it gets to the browser. If you are generating the JS through FM such as in a script block of a html file then what the browser will see is

function abc(){
    var b = document.getElementById("tc").value;
    if(b=="true"){

    }
    else{

    }
}

You can verify this by looking at the source in the browser (for FireFox right click and select View Page Source).
