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 {
    @RemoteAction
    public 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 standardController="Your_Object__c">
    <script>
        function 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);
                    }
                }
            );
        }
    </script>
    <button onclick="executeApexCode();">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 id="lightning-component-container"></div>
    <script>
        $Lightning.use("c:YourApp", function() {
            $Lightning.createComponent(
                "c:YourLightningComponent",
                {},
                "lightning-component-container",
                function(component) {}
            );
        });
    </script>
</apex:page>

In 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.文章来源地址https://www.toymoban.com/news/detail-726333.html
