Javascript 价格销售没有定义。但是，确实如此

我发现错误

PriceSelling

未定义。但事实上，我知道它在页面上，因为它将它记录在控制台中。请帮忙！谢谢

$.get(window.location, function(data){
   var regex=/<span class="it " data-se="item-privatesale-price">([\d,]+)<\/span>/;
   var PriceSelling = data.match(regex)[1];  
    console.log(PriceSelling);
});

function get(name){
   if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
      return decodeURIComponent(name[1]);
} 

if (get('bot') && get('expecting') && get('expecting') == PriceSelling) {
console.log("It's a go!");
document.getElementsByClassName('conf-buy-now btn-primary btn-medium PurchaseButton ')[0].click();
//document.getElementById('conf-confirm-btn').click();
}; 

$.get（窗口、位置、函数（数据）{
var regex=/（[\d，]+）/；
var PriceSelling=data.match（regex）[1]；
控制台日志（价格销售）；
});
函数get（名称）{
if（name=（新的RegExp（'[？&]'+encodeURIComponent（name）+'=（[^&]*））.exec（location.search））
返回组件（名称[1]）；
} 
if（get（'bot'）&&get（'expecting'）&&get（'expecting'）==价格销售）{
log（“开始了！”）；
document.getElementsByClassName（'conf-buy-now btn primary btn medium PurchaseButton'）[0]。单击（）；
//document.getElementById（'conf-confirm-btn'）。单击（）；
}; 

它在传递给

$的回调函数的作用域中定义。get

但它没有在全球范围内定义

你可以

var PriceSelling;

$.get(window.location, function(data){
  var regex=/<span class="it " data-se="item-privatesale-price">([\d,]+)<\/span>/;
  PriceSelling = data.match(regex)[1];  
  console.log(PriceSelling);
});

function get(name){
  if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
    return decodeURIComponent(name[1]);
} 

if (get('bot') && get('expecting') && get('expecting') == PriceSelling) {
  console.log("It's a go!");
  document.getElementsByClassName('conf-buy-now btn-primary btn-medium PurchaseButton ')[0].click();
  //document.getElementById('conf-confirm-btn').click();
}

PriceSelling未在您调用它的范围内定义。为什么它会记录它？它会记录，因为PriceSelling声明和您的console.log在同一范围内。

$.get(window.location, function(data){
  var regex=/<span class="it " data-se="item-privatesale-price">([\d,]+)<\/span>/;
  var PriceSelling = data.match(regex)[1];  
  console.log(PriceSelling);

  function get(name){
    if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
      return decodeURIComponent(name[1]);
  } 

  if (get('bot') && get('expecting') && get('expecting') == PriceSelling) {
    console.log("It's a go!");
    document.getElementsByClassName('conf-buy-now btn-primary btn-medium PurchaseButton ')[0].click();
    //document.getElementById('conf-confirm-btn').click();
  } 
});
