  • Have a child window be notified when parent window goes to a different page?

    - by Heinrich Schmetterling
    i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page. any suggestions? thanks.

  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • What is your most useful C/C++ snippet?

    - by maddizzyro
    Hello all, It seems that every project has an "util" module with various code snippets used throughout other files and which don't fit any particular pattern. I want to improve my "util" library, so please post here the most useful class / function / macro that you use in all your C/C++ projects. Please keep the entries small (under 100 lines) and give only one example per post. Thank you.

  • Jquery prevent dragging of text value

    - by ipr101
    I have a html textbox on which I've bound a function via jQuery to the paste event to prevent users pasting a value into the textbox. This functionality works well. However it is possible to select some text from another textbox on the page and drag it into the textbox in which pastes are prevented. Is there a jQuery event that I can bind to that will prevent users dragging text into the texbox?

  • Doubt in Conditional inclusion

    - by Philando Gullible
    This is actually extracted from my module (Pre-processor in C) The conditional expression could contain any C operator except for the assignment operators,increment, and decrement operators. I am not sure if I am getting this statement or not since I tried using this and it worked.Also for other manipulation a probable work around would be to simply declare macro or function inside the conditional expression,something like this to be precise. Also I don't understand what is the rationale behind this rule. Could somebody explain? Thanks

  • How to get four following text inputs after each checkbox?

    - by Richard Knop
    I am traversing checkboxes like this: $('.day').each(function() { // here I need to get the following 4 text inputs in the HTML // and set some attributes on them }); After every checkbox there are four text input fields (there are also some div, span tags for CSS around them). So inside the loop above I need to get four text input fields that follow the checkbox in the HTML source so I can set some attributes on them. How would I go about that?
