Javascript：动态更改点击具有"window.open"

Question

我想更改onclick的值，我尝试过，但没有成功。有什么帮助吗？

<a href='#' id='social' onClick="">click</a>
document.getElementById("social").onclick = "open_new_window('https://twitter.com/share?url=https%3A%2F%2F"+url+"&amp;via=iguestblogger&amp;text="+title+"');";

注：url、title和open_new_window()已定义，工作正常。

Answer 1

不更改onclick属性的值，只需绑定事件即可。

document.getElementById("social").onclick = function() {
  open_new_window('https://twitter.com/share?url=https%3A%2F%2F'+url+'&via=iguestblogger&text='+title);
};

Answer 2

document.getElementById("social").onclick = function(){open_new_window('https://twitter.com/share?url=https%3A%2F%2F"+url+"&via=iguestblogger&text="+title+"');};

Answer 3

假设url和title以及函数open_new_window已经在前面定义过了，也要注意你的报价

<a href='#' id='social' >click</a>
<script>
document.getElementById("social").onclick = function()
  open_new_window("https://twitter.com/share?url=https%3A%2F%2F"+url+"&amp;via=iguestblogger&amp;text="+encodeURI(title));
  return false;
}
</script>

Answer 4

document.getElementById("social").onclick = open_new_window('https://twitter.com/share?url=https%3A%2F%2F"+url+"&via=iguestblogger&text="+title+"');
