making safari extension in context menu. When over image mouse right click, how i know image url?

safari, safari-extension

Solution

You could try this:

store the whole node into the event's userInfo:

function handleContextMenu(event) {
    safari.self.tab.setContextMenuEventUserInfo(event, event.target);
}

add some global javascript variable to your global.html (e.g. var lastClickedImg),

change your handleContextMenu function to store the event.userInfo in function handleContextMenu to this variable:

function handleContextMenu(event) {
    var query = event.userInfo;
    if (query.nodeName === "IMG") {
        lastClickedImg = query;
        event.contextMenu.appendContextMenuItem("imageSearch", "Search Google with this image");
    }
}

in your function performCommand you will easily get the image's url from lastClickedImg:

lastClickedImg.src

Problem

Making safari extension imageSearch By google. Here is my source. injected.js ``` document.addEventListener("contextmenu", handleContextMenu, false); function handleContextMenu(event) { safari.self.tab.setContextMenuEventUserInfo(event, event.target.nodeName); } ``` global.html ``` <!DOCTYPE HTML> <script type="text/javascript" src="jquery.js"></script> <script> safari.application.addEventListener("contextmenu", handleContextMenu, false); function handleContextMenu(event) { var query = event.userInfo; if (query === "IMG") { event.contextMenu.appendContextMenuItem("imageSearch", "Search Google with this image"); } } safari.application.addEventListener("command", performCommand, false); function performCommand(event) { if (event.command === "imageSearch") { /*How I get image Url??? */ var imageUrl=""; /* var url = "http://images.google.com/searchbyimage?image_url="+imageUrl; var tab = safari.application.activeBrowserWindow.openTab("foreground"); tab.url = url; */ } } ``` My goal is.. if mouse rightclick add "Search by Google With This Image" int the context menu. (clear) and click "Search by Google With This Image" google it. (???) so i want to know image url. What should I do?
