How to Write string in function within a function?

Recommended Posts

function keyE(e,n,v) {// some function here}; function editProp(n) {// the caller is a button with function onClick="editProp('userID')"// n = 'userID'var dStr = document.getElementById(n).innerHTML;document.getElementById('f_' + n).innerHTML = '<input type="text" name="i_' + n + '" id="i_userID" value="' + dStr+ '" onkeypress="keyE(event,' + n + ',this.value)" />'; //error heredocument.getElementById('i_' + n).focus();document.getElementById('i_' + n).setSelectionRange(0,dStr.length);} // debug with Mozilla Firefox 15.0.1 Developer Tools

The editProp(n) function generate error and I don't know how to fix it. The error is at document.getElementById('f_' + n).innerHTML = '<input type="text" name="i_' + n + '" id="i_userID" value="' + dStr+ '" onkeypress="keyE(event,' + n + ',this.value)" />'; The phrase onkeypress="keyE(event,' + n + ',this.value)" generate error "userID is not defined". userID is a string defined in n variable but it detect it as a variable. How to fix it? Thanks for any help provided. errjava.png?psid=1

you need quotes around n in the callback parameter:
'.. onkeypress="keyE(event,\'' + n + '\',this.value)" />';

Success :rofl: . Thanks so much JamesB.
