Question

到目前为止，我在页面末尾有这3个社交按钮。我以为重写相同的功能3次并不是很聪明。我可以团结他们吗？会有用吗？

任何想法如何做到这一点？逻辑上我会这样做： g.src ='http：//apis.google.com/js/plusone.js'，'http：//connect.facebook.net/en_US/all.js#xfbml=1'，'http：// platform .twitter.com / widgets.js';

但我不确定这种方法是否正确......

<script type="text/javascript">
//<![CDATA[
(function(d, t) {
var g = d.createElement(t),
s = d.getElementsByTagName(t)[0];
g.async = true;
g.src = 'http://apis.google.com/js/plusone.js';
s.parentNode.insertBefore(g, s);
})(document, 'script');
//]]>
</script>


<script type="text/javascript">
//<![CDATA[
(function(d, t) {
var g = d.createElement(t),
s = d.getElementsByTagName(t)[0];
g.async = true;
g.src = 'http://connect.facebook.net/en_US/all.js#xfbml=1';
s.parentNode.insertBefore(g, s);
})(document, 'script');
//]]>
</script>


<script type="text/javascript">
//<![CDATA[
(function(d, t) {
var g = d.createElement(t),
s = d.getElementsByTagName(t)[0];
g.async = true;
g.src = 'http://platform.twitter.com/widgets.js';
s.parentNode.insertBefore(g, s);
})(document, 'script');
//]]>
</script>

Answer 1

var scripts = ["http://apis.google.com/js/plusone.js","http://connect.facebook.net/en_US/all.js#xfbml=1","http://platform.twitter.com/widgets.js"];
(function(array) {
   for (var i = 0, len = array.length; i < len; i++)
   {
      var elem = document.createElement('script');
      elem.type = 'text/javascript';
      elem.async = true;
      elem.src = array[i];
      var s = document.getElementsByTagName('script')[0];
      s.parentNode.insertBefore(elem, s);
   }
})(scripts);

这是我的解决方案，在Linux下在Chrome和Mozilla上测试过！

Answer 2

尝试：

<script type="text/javascript">
//<![CDATA[
(function(d, t) {
var gplus = d.createElement(t), fb = d.createElement(t), twt = d.createElement(t),

// google plus
gplus.async = true,
gplus.src = 'http://apis.google.com/js/plusone.js',

// facebook
fb.async = true,
fb.src = 'http://connect.facebook.net/en_US/all.js#xfbml=1',

// twitter
twt.async = true,
twt.src = 'http://platform.twitter.com/widgets.js',    

s = d.getElementsByTagName(t)[0];

s.parentNode.insertBefore(gplus, s);
s.parentNode.insertBefore(fb, s);
s.parentNode.insertBefore(twt, s);
})(document, 'script');
//]]>
</script>

是否有可能将几个异步社交按钮加载器合二为一？
