parent

Consider the following HTML: <div class="foo" id="obj"> I should be changed red <div class="bar" style="color:black;"> I should not be changed red. <div class="foo">I should be changed red.</div> </div> </div> Given a DOM element obj and an expression, how do I go about selecting any children and possibly obj ? I'm looking for something similar to "select descendants" but also including the parent, if it matches the expression. var obj = $("#obj")[0]; //wrong, may include siblings of 'obj' $(".foo", $(obj).parent()).css("color", "red"); //wrong -- excludes 'obj' $(".foo", obj).css("color",

I have a custom UserControl that I am drawing using the GDI+. It is a transparent control which draws small shapes on top of the parent control. All the parent window does is creates the control, gives it a Rectangle in which to draw itself, and then it receives events if the user clicks on the non-transparent areas. The drawing part works perfectly, but right now what I need to do is to as seamlessly as possible forward all MouseMove, MouseClick, etc. events to the parent control IF those events occurred outside the shapes. The shapes are drawn using GraphicsPath, and I am already able to

Having a little trouble on this one. I need a way using Jquery/JS to find the HREF attribute of the enclosing link tag: <a href="something.html"><img src="img1.jpg" class="active"></a> I want to target the img by class and find the value of the 1st preceding href attribute. $("img.active").somethingAwesome().attr("href"); Please show me somethingAwesome() ...help? $("img.active").parent("a").attr("href") will get the direct parent's href attribute, assuming it's an anchor. If there's any depth of containing blocks between the image and the anchor, use instead $("img.active").closest("a").attr(

In PHP, I'm trying to reference a method defined in an object's parent class, from a method inherited from the object's parent class. Here's the code: class base_class { function do_something() { print "base_class::do_something()\n"; } function inherit_this() { parent::do_something(); } } class middle_class extends base_class { function do_something() { print "middle_class::do_something()\n"; } } class top_class extends middle_class { function do_something() { print "top_class::do_something()\n"; $this->inherit_this(); } } $obj = new top_class; $obj->do_something(); The problem is that parent:

I have a "meter" class. One property of "meter" is another class called "production". I need to access to a property of meter class (power rating) from production class by reference .

Is there a way to select a DIV in the parent window using jQuery? For example: Main page contains this, <div id="testdiv"></div> Popup page has a form with some options and an 'Apply' button. When the user clicks apply it affects the style attribute on the main page. Something along the logic of, parent.$("#testdiv").attr("style", content from form); Use the context-parameter $("#testdiv",parent.document) But if you really use a popup, you need to access opener instead of parent $("#testdiv",opener.document) TARKUS I looked for a solution to this problem, and came across the present page. I
