  • Why GLatLng() doesn't receive variables?

    - by David
    Hi, i have the following code to update a google map: function updateit(c1,c2){ alert(c1+"-"+c2); // This works map.setCenter(new GLatLng(c1, c2), 13); // But this doesn't } updateit(37.4419, -122.1419); The alert is working and show the two coordinations, but i think the GLatLng() doesn't receive them, so the map is not updated unless i directly declare them as strings : function updateit(c1,c2){ map.setCenter(new GLatLng(37.4419, -122.1419), 13); // This works } How to fix this problem? Thanks

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  • Use javascript variables in Rails view helpers

    - by Horacio
    Using jqGrid I want to generate delete links for each row in the grid. The standard way to do this is to add the links in the gridComplete callback like shown below: gridComplete: function() { var ids = jQuery("#jobs_table").jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var cl = ids[i]; be = '<%= link_to(image_tag("delete.gif", :border=>0, :size=>"20x22", :alt => "delete"),· { :action => 'destroy', :id => 'cl', :method => :delete}, :class => 'ajax') -%>'; jQuery("#jobs_table").jqGrid('setRowData',ids[i],{workflow_state:be}); } }, Using getDataIDs I get a list of IDs that I can use to generate the delete links. The problem is that this is a javascript call that results in a javascript variable. The question is how can I use this variable "cl" inside rails link_to view helper?

  • Resources for looking up differences in rendering behavior between web-browsers and browser bugs

    - by ICodeForCoffee
    I recently encountered a printing issue in Firefox that eventually turned out to be a problem with the fieldset tag we wrapped the entire page in. (Bugzilla: Bug 471015) All browsers have their own rendering quirks and issues, but it can be very hard to know what's causing different behaviors. Sure, you can Google, but that's often taking a shot in the dark about what you think is causing the problem. It also doesn't stop you from having to sort through multiple complains about the same behavior before you find someone who has the issue your looking for. Are there any websites out there that let you search for rendering behavior issues by browser version, browser function, css tag, or html tag? I've seen this SO Question, Wanted: Resource for documented Cross-Browser differences, but I'd like to find something more detailed that includes browser bugs.

  • jQuery rotator not rotating properly - too much recursion

    - by Matt Nathanson
    I've built a custom jQuery rotator using just basic animation to rotate the 3 Divs (images). I've built the function and then reinitiate the function using it as a call back. Here's the code: function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber-1; if ( featureNumber == 1) {featureNumber2=3} var CurrentFeature2 = "#container" + featureNumber2; $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); $('#container2').stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); var featureNumber3 = featureNumber+1; if ( featureNumber == 3){featureNumber3=1} var CurrentFeature3 = "#container" + featureNumber3; $(CurrentFeature3).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); if (featureNumber ==1) {featureNumber=3} else{featureNumber--}; $(CurrentFeature).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature3).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature2).stop(false, false).delay(4500).animate({'top' : '-330px'}, 25,ImageRotate()); }; It's worth noting that when calling the function again I also tried making another function called ImageRotate2(); and it did the same thing. It loops, but i get all sorts of funkiness. Edit: I've also tried some answers in the replies and they both leave me with recursion errors each second.

  • How do I SEO these keywords?

    - by alex
    I am building a music album search engine. My questions are: How do I figure out which keywords people search the most? Do they search "music album" the most, or "album music" the most? What tool can I use to get this stats? Should I position my website to what people search the most? What about competitors? Please give me some tips on whether I should have the title "music album" or "album search" , depending on number of keyword searches.

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!

  • Execute function every nth second

    - by timkl
    Total JacaScript n00b question right here: I've made this snippet that clicks a link after 10th second: function timeout() { window.setTimeout(function() { $('img.left').click(); }, 1000); setTimeout("timeout()", 1000); } timeout(); My question is, how do I execute this function every 10th second, instead of just once? Is this the best way to do this, or is there some kind of nifty jQuery method that you prefer?

  • jquery: Writing a method

    - by Mark
    This is the same question as this: http://stackoverflow.com/questions/2890620/jquery-running-a-function-in-a-context-and-adding-to-a-variable But that question was poorly posed. Trying again, I'm trying to do something like this: I have a bunch of elements I want to grab data from, the data is in the form of classes of the element children. <div id='container'> <span class='a'></span> <span class='b'></span> <span class='c'></span> </div> <div id='container2'> <span class='1'></span> <span class='2'></span> <span class='3'></span> </div> I have a method like this: jQuery.fn.grabData = function(expr) { return this.each(function() { var self = $(this); self.find("span").each(function (){ var info = $(this).attr('class'); collection += info; }); }); }; I to run the method like this: var collection = ''; $('#container').grabData(); $('#container2').grabData(); The collection should be adding to each other so that in the end I get this console.log(collection); : abc123 But collection is undefined in the method. How can I let the method know which collection it should be adding to? Thanks.

  • Is there a way to exit a Greasemonkey script?

    - by SimpleCoder
    I know that you can use return; to return from a Greasemonkey script, but only if you aren't in another function. For example, this won't work: // Begin greasemonkey script function a(){ return; // Only returns from the function, not the script } // End greasemonkey script Is there a built in Greasemonkey function that would allow me to halt execution of the script, from anywhere in the script? Thank you,

  • Are there known problems with >= and <= and the eval function in JS?

    - by Augier
    I am currently writing a JS rules engine which at one point needs to evaluate boolean expressions using the eval() function. Firstly I construct an equation as such: var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "relation.value"; relation.relatedTrigger.previousValue is the value I want to compare. relation.operator is the operator (either "==", "!=", <=, "<", "", ="). relation.value is the value I want to compare with. I then simply pass this string to the eval function and it returns true or false as such: return eval(equation); This works absolutely fine (with words and numbers) or all of the operators except for = and <=. E.g. When evaluating the equation: relation.relatedTrigger.previousValue <= 100 It returns true when previousValue = 0,1,10,100 & all negative numbers but false for everything in between. I would greatly appreciate the help of anyone to either answer my question or to help me find an alternative solution. Regards, Augier. P.S. I don't need a speech on the insecurities of the eval() function. Any value given to relation.relatedTrigger.previousValue is predefined. edit: Here is the full function: function evaluateRelation(relation) { console.log("Evaluating relation") var currentValue; //if multiple values if(relation.value.indexOf(";") != -1) { var values = relation.value.split(";"); for (x in values) { var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "values[x]"; currentValue = eval(equation); if (currentValue) return true; } return false; } //if single value else { //Evaluate the relation and get boolean var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "relation.value"; console.log("relation.relatedTrigger.previousValue " + relation.relatedTrigger.previousValue); console.log(equation); return eval(equation); } } Answer: Provided by KennyTM below. A string comparison doesn't work. Converting to a numerical was needed.

  • jQuery Address double load on init

    - by dazhall
    Hi All! I'm using jQuery Address to load in my content, but it's doing it twice on the init. I set it up so that if you go to the main category it loads the first image, but it's doing it twice and I'm not sure how to stop it. A fresh pair of eyes would be appreciated! $.address.init(function(event) { $('#carousel-clip a').address(); if(!event.pathNames[0]) { var url = $('#carousel-clip ul li:first a').attr('href').replace('#!/',''); $.address.path(url); } }).change(function(event) { if(event.pathNames[0]) { $.getJSON(location.pathname + 'image/' + event.pathNames[0] + '/', function(data, textStatus, XMLHttpRequest) { handler(data); }); } }); You can see it working here: http://bit.ly/cKftwA Thanks!

  • toggleClass messing something up.

    - by Mathias Nielsen
    Hi I am using playing around with the Pretty-checkboxes-plugin and have a problem. The plugin can be seen here http://aaronweyenberg.com/90/pretty-checkboxes-with-jquery As you can see, this uses two links to select and deselect. I want it to only use one link and then change the class to make it work the other way the next time it is clicked. It should be simple enough. I have been trying to get it working with toggleClass. I simply put in the toggleClass statement so the code looks like so: $(document).ready(function() { /* see if anything is previously checked and reflect that in the view*/ $(".checklist input:checked").parent().addClass("selected"); /* handle the user selections */ $(".checklist .checkbox-select").click( function(event) { event.preventDefault(); $(this).parent().addClass("selected"); $(this).parent().find(":checkbox").attr("checked","checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); $(".checklist .checkbox-deselect").click( function(event) { event.preventDefault(); $(this).parent().removeClass("selected"); $(this).parent().find(":checkbox").removeAttr("checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); }); This works to some extend. The classes toggle just fine, but the rest of the code only works the first time it is run. All subsequent clicks just toggle the class og the link and nothing else. Does anyone have any idea why this is?
