页面加载后如何执行JavaScript？ [英] How to execute JavaScript after page load?

问题描述

我想在页面加载后执行JavaScript函数。目前我有一个commandButton，一切正常。但是如果用户不应该按下按钮会更舒服。

I would like to execute a JavaScript function after the page was loaded. At the moment I have a commandButton and everything works fine. However it would be more comfortable if the user is not supposed to hit the button.

我试过f：event，但是我没有听众，我只有JavaScript函数。此外，body onload对我来说不起作用，因为我只使用高级组件。

I have tried f:event, but I do not have a listener, I have only the JavaScript function. Moreover body onload does not work for me as I use only high level components.

    <ui:define name="content">


        <pm:content>

            <h:inputHidden id="address" value="#{pathFinderBean.address}" />

            <div id="map" style="width: 100%; height: 285px;"></div>

             <p:commandButton type="button" value="Route" onclick="PathFinder.findAndGo()"/>

            <div id="route"></div>

        </pm:content>
    </ui:define>

</ui:composition>

JavaScript函数PathFinder.findAndGo在我的master.xhtml中定义

The JavaScript function PathFinder.findAndGo is defined in my master.xhtml

推荐答案

按如下方式使用JQuery：

Use JQuery as follows:

<script>
    jQuery(document).ready(function() {
        PathFinder.findAndGo();
    });
</script>

更新：

必须是在< ui：define name =content> 。
