Apex组件控制器无法从apex：inputText / inputField获取值

Question

I have a simple custom component that I want to use to send an email. The structure is like this:

<apex:form>
    <apex:actionFunction action="{!sendEmail}" name="sendEmail" />
    <apex:inputField value="{!To}"/>
    <button type="button" onClick="sendEmail();"/>
</apex:form>

and a controller that is like this:

public with sharing class emailComponent{
    public string To { get; set; } 

    public void sendEmail(){
        system.debug(logginglevel.info,To);
    }
}

Now when I fire the actionFunction the correct method is called but the value of "To" will always be null. Even if I set the value in the contructor when I call the method the value will be null. I don't know if this has to do with it being a custom component controller or if there's something else im missing..

Answer 1

将“ rerender”属性添加到apex：actionFunction，它应该开始工作
