  15. Hello There. I'am Making What It Seems Like A Function To Animate The Background Color Of An Element,But I Have A Problem. This Is The Code: <script> function color(id,duration,r_start,g_start,b_start,r_end,g_end,b_end) { var element=document.getElementById(id); var parameter=setInterval(colorGradually,50*duration); function colorGradually() { if (r_start==r_end && g_start==g_end && b_start==b_end) { clearInterval(parameter); } else { for (var i=r_start,var j=g_start,var k=b_start; i<r_end && j<g_end && k<b_end;i++,j++,k++) { element.style.backgroundColor="rgb("+i+","+j+","+k+")"; } } } } </script> <div id="test" style="width:100%;height:200px;background-color:rgb(128,128,128)"></div> <input type="button" onclick="color('test',1,128,128,128,255,255,255)" value="Change"> The Script Isn't Working At All. I've Checked The Script With Esprisma Code Validator And The Code Was Syntactically Valid,But I Can't Recognize The Problem...
  16. So,I'am Creating An Internal Search Engine Which Can Be Used To Search For A Specific Word In The Page You're Browsing. This Engine Makes The Background Color Is Yellow For The Word You're Searching. <!--Taken From W3Schools.com--> <p> The display property sets or returns the element's display type. Elements in HTML are mostly "inline" or "block" elements: An inline element has floating content on its left and right side. A block element fills the entire line, and nothing can be displayed on its left or right side. </p> <p> The display property also allows the author to show or hide an element. It is similar to the visibility property. However, if you set display:none, it hides the entire element, while visibility:hidden means that the contents of the element will be invisible, but the element stays in its original position and size. Tip: If an element is a block element, its display type can also be changed with the float property. </p> <script> var i; function searchFor(keyword) { for (i=0;i<document.querySelectorAll("p").length;i++) { document.querySelectorAll("p").innerHTML=document.querySelectorAll("p").innerHTML.replace(/keyword/gi,"<span style='background-color:yellow;'>"+keyword+"</span>"); } searchFor("display"); </script> How Can I Make It Possible To Pass A String As A Parameter To The searchFor() Function?

  21. Hello, I would like to implement a Javascript applet to display a given frame of a multi-frame TIFF image on a webpage. The multi-frame TIFF image will be stored on a public Gdrive folder and I would like the applet not to download the whole file but only the specific frame to be displayed (for performance since the file will be very large). Is that enabled by the Gdrive API (which functions should be used?) and what Javascript libraries would be the most appropriate for the task?
