How to Effectively Integrate JavaScript Functions into HTML Buttons?

Incorporating JavaScript into HTML Buttons: A Comprehensive Guide

HTML buttons offer a straightforward way to execute JavaScript functions. However, certain nuances may hinder their effectiveness.

1. Defining Event Handling in HTML

The first method involves embedding the function call directly into the HTML code:

<input type="button" value="Capacity Chart" onclick="CapacityChart();">

2. Utilizing DOM Property

Alternatively, the event can be added to the DOM property for the element:

document.getElementById("clickMe").onclick = doFunction;

3. Attaching Event Handler

A third method involves attaching a function to the event handler:

var el = document.getElementById("clickMe");
if (el.addEventListener)
    el.addEventListener("click", doFunction, false);
else if (el.attachEvent)
    el.attachEvent('onclick', doFunction);

4. Potential Issues with CapacityChart Function

In your specific case, the issue may lie within the CapacityChart function. Consider modifying the problematic line below:

CapacityWindow.document.write(s);

to:

CapacityWindow.document.open("text/html");
CapacityWindow.document.write(s);
CapacityWindow.document.close();

5. Browser Compatibility Considerations

Note that some of the code provided may rely on Internet Explorer compatibility. For cross-browser compatibility, replace references to document.all with document.getElementById.
