单击按钮后如何调用javascript函数？

Question

您好，我在单击按钮后调用以下 javascript 时遇到问题。 我还需要一个代码来插入按钮，我可以用它来调用下面的 JS 函数。唯一的要求是在单击按钮之前脚本的结果不应显示在页面中。此外，即使在执行脚本之后，按钮也将保持不变。单击按钮后页面不应重新加载。生成的提要应仅作为页面中的一个部分在按钮下方运行。

    <!-- start feedwind code --><script type="text/javascript">document.write('\x3Cscript type="text/javascript" src="' + ('https:' == document.location.protocol ? 'https://' : 'http://') + 'feed.mikle.com/js/rssmikle.js">\x3C/script>');</script><script type="text/javascript">(function() {var params = {rssmikle_url: "http://news.google.co.in/news?pz=1&cf=all&ned=in&hl=en&topic=n&output=rss",rssmikle_frame_width: "400",rssmikle_frame_height: "500",frame_height_by_article: "0",rssmikle_target: "_blank",rssmikle_font: "Arial, Helvetica, sans-serif",rssmikle_font_size: "12",rssmikle_border: "off",responsive: "off",rssmikle_css_url: "",text_align: "left",text_align2: "left",corner: "off",scrollbar: "on",autoscroll: "on_mc",scrolldirection: "up",scrollstep: "3",mcspeed: "30",sort: "New",rssmikle_title: "on",rssmikle_title_sentence: "Indian Latest News - As it happens",rssmikle_title_link: "",rssmikle_title_bgcolor: "#0066FF",rssmikle_title_color: "#FFFFFF",rssmikle_title_bgimage: "",rssmikle_item_bgcolor: "#FFFFFF",rssmikle_item_bgimage: "",rssmikle_item_title_length: "55",rssmikle_item_title_color: "#0066FF",rssmikle_item_border_bottom: "on",rssmikle_item_description: "on",item_link: "on",rssmikle_item_description_length: "150",rssmikle_item_description_color: "#666666",rssmikle_item_date: "gl1",rssmikle_timezone: "Etc/GMT",datetime_format: "%b %e, %Y %l:%M:%S %p",item_description_style: "text+tn",item_thumbnail: "full",item_thumbnail_selection: "auto",article_num: "15",rssmikle_item_podcast: "off",keyword_inc: "",keyword_exc: ""};feedwind_show_widget_iframe(params);})();</script><div style="font-size:10px; text-align:center; width:350px;"><a href="http://feed.mikle.com/" target="_blank" style="color:#CCCCCC;">RSS Feed Widget</a><!--Please display the above link in your web page according to Terms of Service.--></div><!-- end feedwind code -->

使用 HTML onClick 调用 javascript 函数。还更正了 javascript 并使其可读。注意我已经删除了document.write并替换为https链接，如果您的网站同时使用http和https，您将需要恢复为document.write

<button onClick='onClickFunc();'> Run script
  </button>
