Every time I attempt to access an object in Chrome Developer Tools, I encounter the following error message: VM4939:1 Uncaught TypeError: Cannot read property 'cells' of undefined at :1:13
Here is my code:
<head>
<script>
var new_2ELayout;
function doOnLoad() {
var new_1CLayout = new dhtmlXLayoutObject({
parent: document.body,
pattern: "1C"
});
var new_1CLayoutA = new_1CLayout.cells("a");
</script>
</head>
The reason for this issue is that the variable new_1CLayout is defined within the scope of the doOnLoad() function, making it inaccessible from outside. To resolve this, declare it globally outside the function.
var new_2ELayout, new_1CLayout;
function doOnLoad() {
new_1CLayout = new dhtmlXLayoutObject({
parent: document.body,
pattern: "1C"
});
var new_1CLayoutA = new_1CLayout.cells("a");
} // Be sure to close the function here
// Now you can access new_1CLayout outside the function
There are two approaches in my view to achieve this:
1 - Define the variables outside of the function
var new_2ELayout, new_1CLayout;
2 - Declare global variables
However, the optimal choice is the first method.
