Cms.up = function(base, contentId, origValue, upId) {
upId = upId || "ups";
var updown = $.cookie("_cms_up_" + contentId);
if (updown) {
return false;
}
$.cookie("_cms_up_" + contentId, "1",{path:'/'});
$.get(base + "/content_up.jspx", {
"contentId" : contentId
}, function(data) {
$("#_cms_up_" + upId).text(origValue + 1);
$("#_cms_up_" + upId).addClass('praiseOnclick');
// $("#_cms_up_" + upId).css("background-image","url('"+path+"')").css("background-position","0px 0px");
});
return true;
}
为什么看不懂？ upId = upId || "ups"
------解决方案--------------------
写个script小段就可以测试了，分别让aa ="" 和 aa="123" 得到 bb 和 123
<body>
<script>
var aa = ""
var bb = aa
------解决方案--------------------
"bb";
alert(bb);
</script>
</body>
