Check for a PopUp Blocker
var mine = window.open("room.html", "", "scrollbars=no,menubar=no,height=600,width=800,resizable=no,toolbar=no,location=no,status=no"); if (mine) { var popUpsBlocked = false; mine.close(); } else { var popUpsBlocked = true; //Ironic we use a Popup to notify of a Popup Blocker... alert('Popup Blocker Detected'); }
XHTML Strict Valid Target
function externalLinks() { if (!document.getElementsByTagName) { return; } var anchors = document.getElementsByTagName("a"); for (var i = 0; i < anchors.length; i++) { var anchor = anchors[i]; if (anchor.getAttribute("href") && anchor.getAttribute("rel") == "e") { anchor.target = "_blank"; } } } window.onload = externalLinks;
Check If Flash Player is Installed
var MM_contentVersion = 6; var plugin = (navigator.mimeTypes && navigator.mimeTypes['application/x-shockwave-flash']) ? navigator.mimeTypes['application/x-shockwave-flash'].enabledPlugin : 0; if (plugin) { var words = navigator.plugins['Shockwave Flash'].description.split(" "); for (var i = 0; i < words.length; ++i) { if (isNaN(parseInt(words[i]))) { continue; } var MM_PluginVersion = words[i]; } var MM_FlashCanPlay = MM_PluginVersion >= MM_contentVersion; } else if (navigator.userAgent && navigator.userAgent.indexOf("MSIE") >= 0 && (navigator.appVersion.indexOf("Win") != -1)) { document.write("<SCR' + 'IPT LANGUAGE=VBScript\> \n"); //FS hide this from IE4.5 Mac by splitting the tag document.write("on error resume next \n"); document.write("MM_FlashCanPlay = ( IsObject(CreateObject(\"ShockwaveFlash.ShockwaveFlash.\" & MM_contentVersion)))\n"); document.write("</SCR' + 'IPT\> \n"); } if (MM_FlashCanPlay) { window.location.replace("flash.html"); } else { window.location.replace("noflash.html"); }
Zero Padding RBG to HEX Converter
object.rgb_to_hex = function(r,g,b) { if (r === null || g === null || b === null ) { return false; } return '#'+('0' + r.toString(16)).slice(-2)+('0' + g.toString(16)).slice(-2)+('0' + b.toString(16)).slice(-2); }
Another way:
function tohex(r,g,b) { if (r === null || g === null || b === null ) { return false; } return '#'+('0' + r.toString(16)).slice(-2)+('0' + g.toString(16)).slice(-2)+('0' + b.toString(16)).slice(-2); }
insertAfter and show_attachments
function insertAfter(newElement,targetElement) { //target is what you want it to go after. Look for this elements parent. var parent = targetElement.parentNode; //if the parents lastchild is the targetElement... if(parent.lastchild == targetElement) { //add the newElement after the target element. parent.appendChild(newElement); } else { // else the target has siblings, insert the new element between the target and it's next sibling. parent.insertBefore(newElement, targetElement.nextSibling); } } function show_attachments() { if (document.attachment) document.attachment.abort(); document.attachment = ajax_get({ url: '/cgi-bin/admin/projects/upload.cgi', handler: function (req, args) { var json_resp = eval("("+req.responseText+")"); attachment_result = json_resp.attachment_result; attachment_link = json_resp.attachment_link attachment_filename = json_resp.attachment_filename; attach_div = document.getElementById('attach_div'); if(attach_div) { newDiv = document.createElement("div"); newDiv.innerHTML = "<a target='_blank' href='"+attachment_link+"'>"+attachment_filename+"</a>"; parent_div = document.getElementById("attachment"); document.body.insertAfter(newDiv, parent_div); } } }); }
Control Alt Keystrokes
Code for creating Keystroke Commands, Hotkeys, in Javascript. These Map Control+ALT keystrokes.
var isCtrl = false; var isAlt = false; document.onkeyup=function(e){ if(e.which == 17) isCtrl=false; } document.onkeyup=function(e){ if(e.which == 18) isAlt=false; } document.onkeydown=function(e){ if(e.which == 17) isCtrl=true; if(e.which == 18) isAlt=true; if(e.which == 83 && isCtrl == true && isAlt == true) { //run code for CTRL+ALT+S alert(e.which); return false; } if(e.which == 79 && isCtrl == true && isAlt == true) { //run code for CTRL+ALT+O alert(e.which); return false; } if(e.which == 84 && isCtrl == true && isAlt == true) { //run code for CTRL+ALT+T alert(e.which); return false; } }
