how to add standard textbox command to jqgrid context menu

问题

If context menu is added to jqGrid using Custom values to Context Menu Items in JQgrid and text filed inline editing is used, textbox standard context menu is not available, it is replace with jqGrid context menu.

How to add standard textbox context menu commands ( Undo, Cut, Copy, Paste, Delete, Select all ) to jqGrid conext menu or how to show standard context menu for textbox inline editing?

Update

On inline edit, if standard menu is opened by right clicking on yellow background or in autocomplete box and after that standard browser context menu is opened, custom menu is not closed, two menus appear.

How to fix this ?

回答1:

It's not easy to implement in context menu commands like "Copy", "Paste", ... so I decide to modify my demo from the answer on your previous question. In the new demo the context menu appears only if the page contains no selected text.

The first problem is that the original code of the jquery.contextmenu.js contains the following code fragment:

$(this).bind('contextmenu', function(e) {
  // Check if onContextMenu() defined
  var bShowContext = (!!hash[index].onContextMenu) ? hash[index].onContextMenu(e) : true;
  if (bShowContext) display(index, this, e, options);
  return false;
});

So the contextmenu handler return always false and prevent creating of the standard context menu. I fix the code to the following (you can download full modified code here):

$(this).bind('contextmenu', function(e) {
  // Check if onContextMenu() defined
  var bShowContext = (!!hash[index].onContextMenu) ? hash[index].onContextMenu(e) : true;
  currentTarget = e.target;
  if (bShowContext) {
    display(index, this, e, options);
    return false;
  }
});

The code of createContexMenuFromNavigatorButtons functions described here I modified

onContextMenu: function (e) {
    var rowId = $(e.target).closest("tr.jqgrow").attr("id"), p = grid[0].p, i,
        lastSelId;

    if (rowId && getSelectedText() === '') {
        ...
        return true;
    } else {
        return false; // no contex menu
    }
}

to use getSelectedText() and to create the context menu only if no text is selected. As the result you will be see your custom context menu only if no text is selected and see the standard context menu (which depend on web browser) if the text selection exist:

UPDATED: I modified my bug report about jquery.contextmenu.js with additional information based on the answer. I hope that the changes will be soon in the main code of jquery.contextmenu.js included in the plugins subdirectory.

UPDATED 2: How you can see here all the fixes are already in the main code of jqGrid on the github and in included in the jqGrid 4.3.

UPDATED 3: If you want to have the standard context menu for all enabled <input type="text" ...>, <input type="textarea" ...> and <textarea ...> elements you should just modify a little the code inside of onContextMenu callback. For example

onContextMenu: function (e) {
    var p = grid[0].p, i, lastSelId,
        $target = $(e.target),
        rowId = $target.closest("tr.jqgrow").attr("id"),
        isInput = $target.is(':text:enabled') ||
        $target.is('input[type=textarea]:enabled') ||
        $target.is('textarea:enabled');
    if (rowId && !isInput && getSelectedText() === '') {
        ...

see one more demo where inline editing will be activate by double-click.
