I would like to pass an object as parameter to an Onclick function inside a string. Something like follwing:
function myfunction(obj,parentobj){
var o=document.createElement("div");
o.innerHTML='<input type="button" onclick="somelistener(' + obj + ')" />';
parentobj.appendChild(o.firstChild);
}
Obviously, this doesn't work. Anyone has any idea? THX!
A more complete version, as suggested by @Austin
<!DOCTYPE html>
<html>
<body>
<style type="text/css">
</style>
<p id="test">test</p>
<p id="objectid"></p>
<script>
function test(s){
document.getElementById("test").innerHTML+=s;
}
function somelistener(obj){
test(obj.id);
}
function myfunction(obj,parentobj){
var o=document.createElement("div");
o.innerHTML='<input type="button" onclick="somelistener(' + obj + ')" />';
o.onclick = function () {
someListener(obj)
}
parentobj.appendChild(o.firstChild);
}
myfunction(document.getElementById("objectid"),document.getElementById("test"));
</script>
</body>
</html>
The above example does not work because the output of obj
to text is [Object object]
, so essentially, you are calling someListener([Object object])
.
While you have the instance of the element in o
, bind to it's click using javascript:
function myfunction(obj,parentobj){
var o=document.createElement("div");
o.innerHTML='<input type="button" />';
o.onClick = function () {
someListener(obj)
}
parentobj.appendChild(o.firstChild);
}
