  • How to invoke a method of js object after invoking another method?

    - by Unitpage
    I often saw this code in jQuery. $('div').action1().delay(miliseconds).action2(); I could realize it in one level action in the following code. function $(id) { var $ = document.getElementById(id); $.action1 = function() { }; return $; } How to write the method delay() and action2() so that I could use them this way? $('div').action1().delay(miliseconds).action2();

  • Encapsulate a set of divs with another div in jQuery

    - by lafoaug
    Hi, I am a little stumped with how to do this. I am using jQuery and wish to encapsulate certain sets of divs with a div. For example I have: <div class="group-1">x</div> <div class="group-1">x</div> <div class="group-2">x</div> <div class="group-2">x</div> <div class="group-3">x</div> And wish to end up with: <div id="set-1"> <div class="group-1">x</div> <div class="group-1">x</div> </div> <div id="set-2"> <div class="group-2">x</div> <div class="group-2">x</div> </div> <div id="set-3"> <div class="group-3">x</div> </div> I am able to cycle through each div and add a div around each one but not the way I want above. Any advice appreciate. Thanks.

  • node.js: encrypting data that needs to be decrypted?

    - by fancy
    We are using bcrypt for passwords and data that never needs to be decrypted. What should do to protect other user information that does. For this example lets say that we didn't want a users real name to be in plain text in case someone was to obtain the db. This is somewhat sensitive data but also needs to be called from time to time and displayed in plain text. Is there a simple way to do this?

  • Google Maps API - load the US

    - by hjk
    I am new to google maps api. I'd like suggestions on achieving the following functionality: whenever the page loads, the map will load centered around the US. Imagine a box around the US with given lat/longs specifying the minimum and maximum boundaries. I need the map to load at the appropriate zoom (and zoom needs to be disabled) such that this box composes the entire map. Basically, I'm wondering if there is a function that loads the map based on lat/long boundaries (or some way to acheive this), rather then loading the map given a zoom level.

  • Get backreferences values and modificate these values

    - by roasted
    Could you please explain why im not able to get values of backreferences from a matched regex result and apply it some modification before effective replacement? The expected result is replacing for example string ".coord('X','Y')" by "X * Y". But if X to some value, divide this value by 2 and then use this new value in replacement. Here the code im currently testing: See /*>>1<<*/ & /*>>2<<*/ & /*>>3<<*/, this is where im stuck! I would like to be able to apply modification on backrefrences before replacement depending of backreferences values. Difference between /*>>2<<*/ & /*>>3<<*/ is just the self call anonymous function param The method /*>>2<<*/ is the expected working solution as i can understand it. But strangely, the replacement is not working correctly, replacing by alias $1 * $2 and not by value...? You can test the jsfiddle //string to test ".coord('125','255')" //array of regex pattern and replacement //just one for the example //for this example, pattern matching alphanumerics is not necessary (only decimal in coord) but keep it as it var regexes = [ //FORMAT is array of [PATTERN,REPLACEMENT] /*.coord("X","Y")*/ [/\.coord\(['"]([\w]+)['"],['"]?([\w:\.\\]+)['"]?\)/g, '$1 * $2'] ]; function testReg(inputText, $output) { //using regex for (var i = 0; i < regexes.length; i++) { /*==>**1**/ //this one works as usual but dont let me get backreferences values $output.val(inputText.replace(regexes[i][0], regexes[i][2])); /*==>**2**/ //this one should works as i understand it $output.val(inputText.replace(regexes[i][0], function(match, $1, $2, $3, $4) { $1 = checkReplace(match, $1, $2, $3, $4); //here want using $1 modified value in replacement return regexes[i][3]; })); /*==>**3**/ //this one is just a test by self call anonymous function $output.val(inputText.replace(regexes[i][0], function(match, $1, $2, $3, $4) { $1 = checkReplace(match, $1, $2, $3, $4); //here want using $1 modified value in replacement return regexes[i][4]; }())); inputText = $output.val(); } } function checkReplace(match, $1, $2, $3, $4) { console.log(match + ':::' + $1 + ':::' + $2 + ':::' + $3 + ':::' + $4); //HERE i should be able if lets say $1 > 200 divide it by 2 //then returning $1 value if($1 > 200) $1 = parseInt($1 / 2); return $1; }? Sure I'm missing something, but cannot get it! Thanks for your help, regards. EDIT WORKING METHOD: Finally get it, as mentionned by Eric: The key thing is that the function returns the literal text to substitute, not a string which is parsed for backreferences.?? JSFIDDLE So complete working code: (please note as pattern replacement will change for each matched pattern and optimisation of speed code is not an issue here, i will keep it like that) $('#btn').click(function() { testReg($('#input').val(), $('#output')); }); //array of regex pattern and replacement //just one for the example var regexes = [ //FORMAT is array of [PATTERN,REPLACEMENT] /*.coord("X","Y")*/ [/\.coord\(['"]([\w]+)['"],['"]?([\w:\.\\]+)['"]?\)/g, '$1 * $2'] ]; function testReg(inputText, $output) { //using regex for (var i = 0; i < regexes.length; i++) { $output.val(inputText.replace(regexes[i][0], function(match, $1, $2, $3, $4) { var checkedValues = checkReplace(match, $1, $2, $3, $4); $1 = checkedValues[0]; $2 = checkedValues[1]; regexes[i][1] = regexes[i][1].replace('$1', $1).replace('$2', $2); return regexes[i][1]; })); inputText = $output.val(); } } function checkReplace(match, $1, $2, $3, $4) { console.log(match + ':::' + $1 + ':::' + $2 + ':::' + $3 + ':::' + $4); if ($1 > 200) $1 = parseInt($1 / 2); if ($2 > 200) $2 = parseInt($2 / 2); return [$1,$2]; }

  • jquery to create array from form data

    - by AndrewStevens
    I've been wrestling with this problem for a couple hours now. Essentially, what I need to do is take the following or similar HTML: <div id="excpdivs"> <div class="excpdiv" id="excpdiv0"> Date: <input name="excp[0][date]"> Open: <input name="excp[0][open]"> Close: <input name="excp[0][close]"> </div> <div class="excpdiv" id="expdiv1"> Date: <input name="excp[1][date]"> Open: <input name="excp[1][open]"> Close: <input name="excp[1][close]"> </div> and get an array similar to the following to a php script: Array ( [0] => Array ( [date] => 2012-09-15 [open] => 3:00 [close] => 5:00 ) [1] => Array ( [date] => 2012-09-16 [open] => 2:00 [close] => 5:00 ) ) My main problem is getting the values from the input elements. My latest attempt is the following: var results = []; $(".excpdiv").each(function(){ var item = {}; var inpts = $(this).find("input"); item.date = $(inpts.get(0)).val(); item.open = $(inpts.get(1)).val(); item.close = $(inpts.get(2)).val(); results.push(item); }); Am I on the right track or am I hopelessly lost?

  • How to keep a floating div centered on window resize (jQuery/CSS)

    - by Jimbo
    Is there a way (without binding to the window.resize event) to force a floating DIV to re-center itself when the browser window is resized? To help explain, I imagine the pseudocode would look something like: div.left = 50% - (div.width / 2) div.top = 50% - (div.height / 2) UPDATE My query having been answered below, I wanted to post the final outcome of my quest - a jQuery extension method allowing you to center any block element - hope it helps someone else too. jQuery.fn.center = function() { var container = $(window); var top = -this.height() / 2; var left = -this.width() / 2; return this.css('position', 'absolute').css({ 'margin-left': left + 'px', 'margin-top': top + 'px', 'left': '50%', 'top': '50%' }); } Usage: $('#mydiv').center();

  • Get Flickr Sets

    Hi everyone. Usual stuff, Googled forever, looked on here, no help. Yet. What I want is to list the sets of photos I have on Flickr. Nice & simple, it would seem. I want the 'title image' (the one used as the thumb for it on Flickr its self), the title and URL. Can't be that hard, can it? The language of choice is PHP (5.1.6), or JS (jQuery if possible). Both are good.

  • Disable Dojo validation on certain fields

    - by Eric LaForce
    I would like to disable client side validation on certain fields in my user form. Currently I have two sets of fields that are displayed depending on the value of a previous drop down list. i.e. if the drop down list is set to value "A" 1 new field appears in the form. If the drop down list is set to value "B" 3 new fields appear in the form (mutually exclusive from the new form field when "A" is selected). Currently my Dojo client side validation fails because the fields that are not shown to the user (and thus no data can be inserted into those fields) fails to validate. Currently I determined that I can set the "validate" attribute to return true like so: <input type="text" id="companycity" name="companycity" class="textinput" value="<?php echo set_value('companycity'); ?>" style="<?php if(isset($errorData['companycity'])){echo $errorData['companycity'];} ?>" dojotype="dijit.form.ValidationTextBox" required="true" trim="true" validate='return true'" regexp="([a-zA-Z]{1,25})" invalidMessage="Invalid value. Must be between 1 and 25 alphabetic characters long."> This fixes my issue for hidden fields. However this now means that no validation is performed when this field becomes visible to the user (i.e. the validate attribute is still set to return true). I have tried removing the validate property when a field is displayed to the user like so: dijit.byId('companycode').attr('validate',''); This just set the attribute to nothing. This however gives errors in firebug saying validate method not found, so I take that to mean I did not remove this attribute correctly or removing this attribute is not the appropriate way to do this. I have also looked at overriding the validator method here but this doesnt seem like what I want either. I do not want to have to rewrite all the validation methods in place of dojo's. I just want dojo not to validate if the field is not visible to the user. Thanks for any advice or help.

  • How do I automatically update hundreds of images in an HTML page using jquery?

    - by Chris
    I have an HTML page where I want to refresh a lot of images every 30 seconds after the HTML page has been downloaded. I understand how to do this with Jquery and a single image, but I want to use about 200 custom urls to determine the current image to display for over 200 images. I need to find an efficient way to have jquery call the custom url associated with each image to download the url for the needed image as it changes, and then update the image in the page when it changes. Current hyperlink example to demonstrate the custom urls. <A href="/urlThatReturnsCurrentImageURL/1234/4567">link to url for image</A> Each custom url will return an image tag like this (or any other text that makes this simpler for jquery) <img src="/static/someImage.jpg"> What is the simplest way to have jquery call the custom url for each image to download the image url, image html, or some other text that jquery can use to download the right image every 30 seconds? Please keep in mind that I will have about 200 of these on a page.

  • Can I delay window.open()?

    - by Jisaak
    So here is my basic problem. The user clicks the save button. Use Ajax to save the content via code-behind. THEN open a new window that loads the content from the DB. I just need a way to not open the window until the content has been saved. Right now it immediately opens a new window and the content isn't all saved yet. Any ideas?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();
