Calling a javascript function that contains dynamic parameters

Question

I am trying to call a javascript function that contains dynamic variable as a parameter. I think i am failing in the syntax to get this particular function executed. I have tried a few combinations and none of them seem to work. Please can someone advise..

 for( i=0; i<succeedList.length; i++){
     var file_uniq_id = succeedList[i].filename_uniq;

 //Creating dynamic button
 var subm_btn = document.createElement("INPUT");
 subm_btn.setAttribute("onclick", "UploadMyScript.submitTitle(this.id,'+file_uniq_id+')");
 p_titleBtn.appendChild(subm_btn);
}



 UploadMyScript.submitTitle = function(id, uniqID){
 // Does something ....
 }

My problem is I cannot appear to pass on the 'file_uniq_id' value to UploadMyScript.submitTitle().

subm_btn.setAttribute("onclick", "UploadMyScript.submitTitle(this.id,'+file_uniq_id+')"); contains a string as the second parameter. You probably want subm_btn.setAttribute("onclick", UploadMyScript.submitTitle(this.id,'+file_uniq_id+')); — akshay

because you are not concatenating correctly because you used the wrong quote to end the string, it should be: "+file_uniq_id+" — Patrick Evans

What does I cannot appear to pass on the 'file_uniq_id' value to UploadMyScript.submitTitle(). mean? What happens when you try? Do you get an error? What is the error? What line causes it? — Code-Apprentice

Why not use an event listener ?

subm_btn.addEventListener('click', function () { 
    UploadMyScript.submitTitle(subm_btn.id, file_uniq_id); },
false);

When i use this event listener. The error that i am getting back is 'Uncaught ReferenceError: file_unique_id is not defined'.

i am sorry i do not understand. I pretty much cut and paste your code for the event listener instead of the code i used to listen for the onclick event therefore i do pass on the file_uniq_id variable.

Check the edit. I initially wrote file_unique_id, but the correct one is file_uniq_id - Notice the lack of ue in the variable name? I would suggest to read on event listeners.
