单击按钮后如何调用javascript函数？

Question

Hi i'm having problem in calling the below javascript after click of a button. I also need a code to insert button with which I can call the below JS function. The only requirement is that the result of the script should not display in the page before click of a button. Further, the button will stay at its position unchanged even after the execution of the script. The page shouldn't reload after clicking on the button. The resultant feed should run below the button only as a section in the page.

    <!-- 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 -->

Quick help needed please.

Using the HTMLs onClick to call a javascript function. Also corrected the javascript and made it readable. Note I have removed the document.write and replace with the https link, if your site uses both http and https, you will need to revert back to the document.write

 <button onClick='onClickFunc();'> Run script </button> <!-- start feedwind code --> <script type="text/javascript" src="https://feed.mikle.com/js/rssmikle.js"></script> <script type="text/javascript"> function onClickFunc() { 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); } document.write(" <button onClick = 'onClickFunc();' > Run script < /button>"); </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 -->
