求教一个函数嵌套中断的问题？ 第二个函数我是想当成公共函数来调用Ask for advice on the problem of function nesting interrupt? I want to call the second function as a public function

  submitChangeFun:function(e){    console.log(e.detail.value.change);    let t = this;    // 输入的值    let changeData = e.detail.value.change;    // 调用判断输入的值是否为空函数    t.publicPopup(changeData);    // 判断不为空时再继续执行    console.log('判断不为空时再继续执行');  },  // 判断输入的值是否为空函数  publicPopup:function(inputData){    if(inputData==""){      wx.showToast({        title: '请输入后再点击',        icon:'none'      })      return false;    }  }

The second function I want to call the second function as a common function is to judge the value entered by the first function is empty. In the first function, I call the second judgement function, and how to interrupt the second function when judging the first function is empty, and stop the remaining code in the first function.   submit ChangeFun:function (e){     console.log (e. detail.value.change ）; let t = this; / / enter the value let changedata = E detail.value.change ; / / call the function t.publicpopup (changedata) to judge whether the input value is empty; / / continue the execution if it is not empty console.log ('continue to execute if it is not empty ');}, / / judge whether the input value is an empty function PU blicPopup:function (inputData){    if(inputData==""){       wx.showToast ({Title: 'please input and click',         icon:'none'      })      return false;    }  }
