JSP フラグメントのページ読み込み時に JavaScript 関数を呼び出す方法

Calling JavaScript Functions on Page Load

When working with JSP fragments, it can be challenging to call JavaScript functions on page load using the traditional onload attribute due to the lack of a body element. However, there is an alternative approach that can be used to achieve the same result: assigning an anonymous function to the onload event handler.

To implement this solution, follow these steps:

1. Define the function you want to execute when the page loads.
2. Create an anonymous function that calls your function:

window.onload = function() {
  yourFunction();
};

3. Assign the anonymous function to the window.onload event handler.

This anonymous function will be invoked when the page finishes loading. You can pass parameters to your function by including them within the parentheses, as demonstrated in the following example:

window.onload = function() {
  yourFunction(param1, param2);
};

Using this method, you can call JavaScript functions during page load without modifying the JSP fragment's structure. It provides a flexible and effective way to dynamically populate portions of the page with data received from the server.
