Question

我有一个JQuery代码，它将引用（在单击按钮时随机生成）传递给twitter。但是，当您打开新窗口以发布推文时，它会显示未定义的值，与实际报价相反。

以下是代码：

$(document).ready(function(){  
  var result;
function getQuotes(){ 

  var quotes = [ "Thousands of candles can be lighted from a single candle, and the life of the candle will not be shortened. Happiness never decreases by being shared.-\n Buddha",
"Happiness is the art of never holding in your mind the memory of any unpleasant thing that has passed.\n-Unknown",
"To be happy, we must not be too concerned with others.\n-Albert Camus",
"If you want happiness for an hour — take a nap.If you want happiness for a day — go fishing.If you want happiness for a year — inherit a fortune.If you want happiness for a lifetime — help someone else."]

var result = quotes[Math.floor(Math.random() * quotes.length)]; 

document.getElementById("stuff").innerHTML = result; 

}
  $("#tweet").on('click',function(){
  window.open("http://www.twitter.com/intent/tweet?text="+result);

});
  $(document).on('click', '#quotes', function() {
    getQuotes();
});

  });

Answer 1

由于使用result两次，您有两个不同的var变量。唯一获得值集的是getQuotes()

中的本地值

在getQuotes()之外声明的其他内容始终未定义。

尝试更改

var result = quotes[Math.floor(Math.random() * quotes.length)];

要

result = quotes[Math.floor(Math.random() * quotes.length)];

将文本传递给twitter web intent
