salesforce 闪电组件初始化函数调用

Question

我正在尝试在 salesforce 商机页面中显示模式弹出窗口之前检查一些内容。当我调用 doInit 函数时，按钮处理函数停止工作。我的密码是

<aura:component implements="force:lightningQuickActionWithoutHeader,force:hasRecordId,force:appHostable,flexipage:availableForRecordHome,force:hasRecordId,force:hasSObjectName" access="global">
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <b>This is recordID {!v.recordId} </b><br/>
  Are you sure you want to proceed?
  <div class="slds-align_absolute-center">
    <lightning:button
      label="No"
      variant="destructive"
      onclick="{!c.handleNo}"
    ></lightning:button>
    <lightning:button label="Yes" onclick="{!c.handleYes}"></lightning:button>
  </div>
</aura:component>

控制器是

(   {
    
    doInit:function(component,event,helper){
   alert(component.get("v.recordId"));
  }
},

    {
  handleNo: function (component, event, helper) {
    var urlEvent = $A.get("e.force:navigateToURL");
    urlEvent.setParams({
      url: "/apex/NQuote",
      isredirect: "true"
    });
    urlEvent.fire();
  },

  handleYes: function (component, event, helper) {
    var urlEvent = $A.get("e.force:navigateToURL");
    urlEvent.setParams({
      url: "/apex/TestPage",
      isredirect: "true"
    });
    urlEvent.fire();
  }
});

您的控制器格式不正确。格式基本上应该是这样的 JSON：

{
    method1 : function (component, event, helper){},
    method2 : function (component, event, helper){}
}

doInit 方法后有额外的大括号。应该是这样的：

({
  doInit: function (component, event, helper) {
    alert(component.get("v.recordId"));
  },
  handleNo: function (component, event, helper) {
    var urlEvent = $A.get("e.force:navigateToURL");
    urlEvent.setParams({
      url: "/apex/NQuote",
      isredirect: "true"
    });
    urlEvent.fire();
  },

  handleYes: function (component, event, helper) {
    var urlEvent = $A.get("e.force:navigateToURL");
    urlEvent.setParams({
      url: "/apex/TestPage",
      isredirect: "true"
    });
    urlEvent.fire();
  }
});
