使用JavaScript Remoting链接JavaScript按钮到Apex代码…在Salesforce中你可以通过自定义JavaScript按钮或链接来触发Apex代码的执行。这可以通过使用JavaScript Remoting或Visualforce页面来实现。以下是一些步骤来将JavaScript按钮与Apex代码链接起来
使用JavaScript Remoting链接JavaScript按钮到Apex代码
创建Apex类首先创建一个Apex类其中包含你要执行的Apex代码。这个Apex类需要使用RemoteAction注解来标记方法以便从JavaScript中调用它。
public class MyApexController {RemoteActionpublic static String executeApexCode() {// 在这里编写你的Apex代码// 返回任何结果return Apex code executed successfully;}
}创建JavaScript按钮在对象的设置中创建一个自定义JavaScript按钮。在按钮的JavaScript代码中使用JavaScript Remoting来调用Apex代码。下面是一个示例按钮的代码
{!REQUIRESCRIPT(/soap/ajax/41.0/connection.js)}
{!REQUIRESCRIPT(/soap/ajax/41.0/apex.js)}var result sforce.apex.execute(MyApexController, executeApexCode, {});// 处理Apex代码执行的结果
alert(result);关联按钮将这个JavaScript按钮与你的对象相关联以便在记录详情页上显示它。
使用Visualforce页面链接JavaScript按钮到Apex代码
创建Visualforce页面创建一个Visualforce页面其中包含你的JavaScript按钮。在Visualforce页面中你可以使用apex:page标签的standardController属性指定对象然后在页面中包含JavaScript按钮。
apex:page standardControllerYour_Object__cscriptfunction executeApexCode() {Visualforce.remoting.Manager.invokeAction({!$RemoteAction.MyApexController.executeApexCode},function(result, event) {if (event.status) {// 处理Apex代码执行的结果alert(result);} else {// 处理错误alert(Error: event.message);}});}/scriptbutton onclickexecuteApexCode();Execute Apex Code/button
/apex:page关联Visualforce页面在对象的设置中创建一个新的JavaScript按钮或链接然后将其链接到上面创建的Visualforce页面。
这些步骤将使你能够通过JavaScript按钮或链接执行Apex代码。确保在Apex代码中包含所需的逻辑并根据需要处理结果。同时确保在按钮或链接的可见性和访问控制方面进行适当的设置以确保只有授权的用户可以执行Apex代码。
Calling a Lightning component from a Classic custom button involves a slightly different approach than doing it in Lightning Experience. Here’s how you can achieve this: Create a Visualforce Page: To bridge the gap between Classic and Lightning components, you can create a Visualforce page that contains your Lightning component. Go to “Setup.”In the Quick Find box, enter “Visualforce Pages” and select it.Click “New” to create a new Visualforce page. Here’s an example of what the Visualforce page might look like: apex:page apex:includeLightning /div idlightning-component-container/divscript$Lightning.use(c:YourApp, function() {$Lightning.createComponent(c:YourLightningComponent,{},lightning-component-container,function(component) {});});/script
/apex:pageIn this example, replace c:YourApp with the name of your Lightning app (if applicable) and c:YourLightningComponent with the name of your Lightning component. Create a Custom Button in Classic: Navigate to the object (e.g., Account, Contact) for which you want to add the custom button.In the object’s page, go to the “Buttons, Links, and Actions” section and click “New Button or Link.” Choose Button Behavior: Select “Visualforce Page” as the content source.Choose the Visualforce page you created in step 1 from the dropdown list. Configure Button Properties: Give your button a name.Optionally, specify a label for the custom button that will appear on the object’s page layout.Configure other properties as needed, such as behavior and display options. Add the Button to Page Layout: Save the custom button.After saving, add the button to the desired page layout. You can do this by editing the page layout for the object and dragging the button from the “Mobile Lightning Actions” section to the “Salesforce Classic Actions” section. Test the Custom Button: Save the page layout.Go to the record detail page for the object you modified in Classic.You should see your custom button (with the label you specified) on the page.Click the button to execute the Visualforce page, which in turn will load your Lightning component.
This approach leverages a Visualforce page as a bridge between Classic and Lightning components. When the custom button is clicked, it loads the Visualforce page, which then embeds and initializes your Lightning component.
