wicket 6:页面加载后调用javascript函数 [英] wicket 6: calling javascript function after page load

问题描述

这看起来很简单，但在页面加载后(在扩展 WebPage 的页面上)，我找不到如何从 wicket 调用 javascript 函数的示例.任何人都可以举例说明如何去做吗?

This seems so simple, yet I cannot find an example of how to call javascript function from wicket, after the page is loaded (on page that extends WebPage). Can anyone give example on how to go that?

推荐答案

您可以让 javascript 为您做到这一点

You can have javascript do that for you

window.onload = function () {
// do stuff here
}

如果您需要 javascript 函数中检票口页面的参数，您可以覆盖 renderHead 并在那里添加函数:

If you need parameters from your wicket page in the javascript function you can override renderHead and add the function there:

@Override
public void renderHead(IHeaderResponse response)
{
    super.renderHead(response);
    String bar = "something";
    response.render(JavaScriptHeaderItem.forScript("window.onload = function () {var foo='" + bar + "'}"));
    // or
    response.render(OnDomReadyHeaderItem.forScript("functionToCall(" + bar + ");") ;
}
