  • Sorting Multidimensional Array with Javascript: Integers

    - by tkm256
    I have a 2D array called "results." Each "row" array in results contains both string and integer values. I'm using this script to sort the array by any "column" on an onclick event: function sort_array(results, column, direction) { var sorted_results = results.sort(value); function value(a,b) { a = a[column]; b = b[column]; return a == b ? 0 : (a < b ? -1*direction : 1*direction) } } This works fine for the columns with strings. But it treats the columns of integers like strings instead of numbers. For example, the values 15, 1000, 200, 97 would be sorted 1000, 15, 200, 97 if "ascending" or 97, 200, 15, 1000 "descending." I've double-checked the typeof the integer values, and the script knows they're numbers. How can I get it to treat them as such?

  • Returning a private variable in JavaScript

    - by enrmarc
    I don't know why console.log(Set.current_index) shows 0 instead of 3. var Set = (function() { var set = []; var index = 0; function contains(set, e) { for (var i = 0; i < set.length; i++) { if (set[i] === e) { return true; } } return false; } var add = function(e) { if (!contains(set, e)) { set[index++] = e; } } var show = function() { for (var i = 0; i < set.length; i++) { console.log(set[i]); } } return { add: add, show: show, current_index: index }; })();? Set.add(20); Set.add(30); Set.add(40); Set.show(); console.log(Set.current_index);

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • JavaScript (jQuery) Regular Expression for searching through an array

    - by CoryDorning
    First and foremost, I do not know RegEx but am trying to piece something together to make this work. Just wanted you to be forewarned. ;) Anyways, I'm trying to create a regular expression to take a word from an array and see if it matches a word in another array. I only want the search to return true if the keyword array string contains the searchTerm word. (i.e. oneone would be false, so would ones). Any help is GREATLY appreciated. var searchTerm = ['one','two','three']; var keywords = ['String which contains one', 'This string is 2', 'Three is here']; var keywordIndex; // loop through each keyword array $.each(keywords, function(i) { $.each(searchTerm, function(j) { var rSearchTerm = new RegExp('\b' + searchTerm[j] + '\b',i); // if search term is found, swap accordion div content if (keywords[i].search(rSearchTerm) > -1) { keywordIndex = i; // grouping keyword is in } }); // end searchTerm loop }); // end keyword loop

  • Adding an additional click event to every element (JavaScript / jQuery)

    - by Gausie
    I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*').click(function() { //do something }); would accomplish my goal, but is that the best way? Also, would that overwrite other click functions assigned to the elements?

  • javascript location.hash refreshing in IE

    - by aepheus
    I need to modify the hash, remove it after certain processing takes place so that if the user refreshes they do not cause the process to run again. This works fine in FF, but it seems that IE is reloading every time I try to change the hash. I think it is related to other things that are loading on the page, though I am not certain. I have an iframe that loads (related to the process) as well as some scripts that are still being fetched in the parent window. I can't seem to figure out a good way to change the hash after all the loading completes. And, at the same time am not even positive that it is related to the loading. Any ideas on how to solve this?

  • Asynchronous javascript issue

    - by amit
    I am trying to create a function which takes values from various html elements of the page to create a string and pass on to a variable. now this works great for all browsers except IE 8 and 9. IE tends to skip the part of fetching the values and goes straight to the variable and finds nothing.. is there a way to sync it all so that it works in IE? function seturl() { var qstring = returnQString(); $('span.keyword').text($.trim($('#hdnKeyWord').attr('value'))); $('input.search_box').attr('value', $.trim($('#hdnKeyWord').attr('value'))); $('#hdnSearchKeyword').attr('value', $.trim($('#hdnKeyWord').attr('value'))); $(".search_box").val($.trim($("#hdn_span_hdnKeyWord").text())); $(".header_inner input[type='text']").focus(); $(".search_term input[type='text']").focus(); $('#locationurl').attr('value', qstring); } function returnQString(){ var qstring = $.trim($('#locationurl').attr('init')); //initial value of the url qstring += "?type=" + $('#hdnSTSearch').attr('value'); // type of handler hit qstring += "&keyword=" + encodeURIComponent($('#hdnKeyWord').attr('value')); // keyword addition qstring += "&pagestart=" + $('#current_page').attr('value'); // pagestart(current page) addition qstring += "&pagesize=" + $('#show_per_page').attr('value'); // per page size addition qstring += "&facets=" // facetsearch $.each(selectedFilter.items, function (index, value) { qstring += value.filter + ","; }); qstring += "&selectedSection=" + selectedSection // Section Select return qstring; }

  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.
