  • JQuery - remove the chars not matching regEx

    - by JQueryBeginner
    Hi All, I am trying to use jquery for validating forms. This is the pattern that is allowed in a text box for a user. var pattern = /^[a-zA-Z0-9!#$&%*+,-./: ;=?@_]/g; If the user types anything else other than this then that has to be replaced with a "". $(document).ready(function() { $('#iBox').blur(function() { var jVal = $('#iBox').val(); if(jVal.match(pattern)) { alert("Valid"); } else { alert("New "+jVal.replace(!(pattern),"")); } }); }); }); But the replace function does not work this way.

  • Regular expression Not working properly n case of multiple trailing ]]]]

    - by ronan
    I have the requirement that in a textbox a user can jump to the next word enclosed in [] on a tab out for example Hi [this] is [an] example. Testing [this] So when my cursor is at Hi and I do a tab out , the characters enclosed in the [this] are highlighted and when I again do a tabl out th next characters enclosed in following [an] are highlighted. This works fine Now the requirement is whatever the text including the special chars between [] needs to be highlighted case 1: when I have trailing ]]], it only highlights leading [[[ and ignores ]]]] e.g case 2: In case of multiple trailing ] e.e [this]]]] is [test], ideally one a single tabl out from this , it should go to next text enclosed in [] but a user has to tab out 4 times one tab per training ] to go to next [text] strong text The code is $(document).ready(function() { $('textarea').highlightTextarea({ color : '#0475D1', words : [ "/(\[.*?\])/g" ], textColor : '#000000' }); $('textarea').live('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { var currentIndex = getCaret($(this).get(0)) selectText($(this), currentIndex); return false; } }); }); function selectText(element, currentIndex) { var rSearchTerm = new RegExp(/(\[.*?\])/); var ind = element.val().substr(currentIndex).search(rSearchTerm) currentIndex = (ind == -1 ? 0 : currentIndex); ind = (ind == -1 ? element.val().search(rSearchTerm) : ind); currentIndex = (ind == -1 ? 0 : currentIndex); var lasInd = (element.val().substr(currentIndex).search(rSearchTerm) == -1 ? 0 : element.val().substr(currentIndex).indexOf(']')); var input = element.get(0); if (input.setSelectionRange) { input.focus(); input.setSelectionRange(ind + currentIndex, lasInd + 1 + currentIndex); } else if (input.createTextRange) { var range = input.createTextRange(); range.collapse(true); range.moveEnd('character', lasInd + 1 + currentIndex); range.moveStart('character', ind + currentIndex); range.select(); } } function getCaret(el) { if (el.selectionEnd) { return el.selectionEnd; } else if (document.selection) { el.focus(); var r = document.selection.createRange(); if (r == null) { return 0; } var re = el.createTextRange(), rc = re.duplicate(); re.moveToBookmark(r.getBookmark()); rc.setEndPoint('EndToStart', re); return rc.text.length; } return 0; } Please let me know to handle two above cases

  • Is it possible to set different select2 parameters at different times?

    - by ReiMasuro
    From playing around I can see that this code $("#Selected3").select2({ minimumInputLength: 3 }); $("#Selected3").select2({ placeholder: "Show a placeholder" }); will show me the placeholder but remove the minimumInputLength parameters value. Does anyone know a way please that this example could be modified so that the placeholder will be added without losing the minimum..Length value. Any answers will need to allow for the possibility of the statements being in separate files, i.e. one on the page and another in a referenced .js file. I am aware that this would be much easier if I set all the parameters at once, e.g. $("#Selected3").select2({ minimumInputLength: 3, placeholder: "Show a placeholder" }); but I am working within a framework which won't currently allow that. EDIT: For anyone who is willing to give this a shot but doesn't know select2 the library comes from here Select2 on GitHub

  • Javascript or jquery replace text

    - by ngreenwood6
    I need to replace some text that is on the page within the body tag. I am using javascript but have jquery available if needed. I basically need to replace test® (test with the registered trademark) with TEST® or tests® with TESTS® and it could even be test with TEST® or tests with TESTS®. I am able to uppercase them but its not liking to work for me with the ® sign, it wants to put duplicates on ones that already have it. Basically anything on the page that has the word test or tests should be TEST® or TESTS® if it is plural. Any help is appreciated.

  • JQuery post to php

    - by RussP
    Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

  • jQuery delay doesn't work as expected

    - by Chris
    I have the following jQuery code $("#dropdown").hover(function() { $(this).stop(true,true).fadeTo('fast',1); $("#options").stop(true,true).slideDown(); }, function() { $(this).delay(1000).stop(true,true).fadeTo('fast',0.1); $("#options").delay(1000).stop(true,true).slideUp(); } ); What I expect to happen is when the mouse leaves #dropdown it will wait 1 second before continuing. This is not happening. What I am trying to achieve, in case there is a better way, is to leave the drop down menu visible for a second or two after moving your mouse and I would also like to prevent the events from happening again to prevent artifacts and "funnies" if you were to move the mouse over and out from the div very quickly

  • Detect all changes to a <input type="text"> (immediately) using JQuery

    - by Dustin Boswell
    There are many ways the value of a <input type="text"> can change, including: keypresses copy/paste modified with JavaScript auto-completed by browser or a toolbar I want my JavaScript function to be called (with the current input value) any time it changes. And I want it to be called right away, not just when the input loses focus. I'm looking for the cleanest and most robust way to do this across all browsers (using jQuery preferably). Example use case: On the Twitter Signup page, the username field's value gets shown in the url "http://twitter/username" below it.

  • JQuery+Java setting field value with val() + single quote

    - by Fabio K
    I have a problem setting the value of a textarea element with jquery's val(). Basically, I have a JSP file which receives a string parameter called 'text'. Java code: String text = (String) request.getParameter('text'); Now I want my textarea element to receive this text: Javascript code: $('#textarea_id').val('<%=text%>'); It works when my text doesnt contain quotes single quotes (and possibly other chars). For example, for text = test' this error happens: Uncaught SyntaxError: Unexpected token ILLEGAL $('#textarea_id').val('test''); I hope you guys understand. I need a way to encode this value... i tried using escape so the quote is replaced by %27, but after unescaping its replaced again and the error happens. Thanks!

  • Jquery Validation Central Message Many Errors

    - by Iamjon
    Hi everyone, I have a form that is being valdated with the Jquery Validation Plugin. I have managed to get a centeral message "Please Recheck the form", and to have the input focus on the first error. To get this, I had to override the default message of each of the errors. I was wondering if anyone could help me figure out how I can have it display the error message associated with the first error input instead of a general error message. Here is the code: $("#Help-A-Noobie-Form" ).validate({ invalidHandler: function(form, validator) { $(this).find(":input.error:first").focus(); var message = 'Please Recheck The Form' ; $("#Help-A-Noobie-Form #Message p").addClass('red').html(message); }, showErrors: function(errorMap, errorList) { this.defaultShowErrors(); }, rules: { required:true, email: {email:true}, phone: {digits:true} }, messages: { email: "", phone: "", lastname: "", firstname: "", required:"" } })

  • Using Jquery to check if a URL is valid

    - by user102533
    A long running background process creates a text file to indicate the completion of the process. From the frontend, I'd need to check every few seconds if the text file has been created or not. I am doing this check from However the file is created in http://DomainB.com/Mytext.txt Can someone help me write a jquery script that checks for a file across domain? PS: Currently, I am doing a ajax postback that executes a WebMethod in ASP.NET that creates HttpWebRequest. This works functionally, but I have major performance problems. So, I need a light weight way of finding if a URL is valid or not.

  • Is it possible to make JQuery keydown respond faster?

    - by Drew Paul
    I am writing a simple page with JQuery and HTML5 canvas tags where I move a shape on the canvas by pressing 'w' for up, 's' for down, 'a' for left, and 'd' for right. I have it all working, but I would like the shape to start moving at a constant speed upon striking a key. Right now there is some kind of hold period and then the movement starts. How can I get the movement to occur immediately? Here the important part of my code: Your browser does not support the HTML5 canvas tag. start navigating coords should pop up here key should pop up here var c=document.getElementById("myCanvas"); var ctx=c.getContext("2d"); //keypress movements var xtriggered = 0; var keys = {}; var north = -10; var east = 10; var flipednorth = 0; $(document).ready(function(e){ $("input").keydown(function(){ keys[event.which] = true; if (event.which == 13) { event.preventDefault(); } //press w for north if (event.which == 87) { north++; flipednorth--; } //press s for south if (event.which == 83) { north--; flipednorth++; } //press d for east if (event.which == 68) { east++; } //press a for west if (event.which == 65) { east--; } var msg = 'x: ' + flipednorth*5 + ' y: ' + east*5; ctx.beginPath(); ctx.arc(east*6,flipednorth*6,40,0,2*Math.PI); ctx.stroke(); $('#soul2').html(msg); $('#soul3').html(event.which ); $("input").css("background-color","#FFFFCC"); }); $("input").keyup(function(){ delete keys[event.which]; $("input").css("background-color","#D6D6FF"); }); }); </script> please let me know if I shouldn't be posting code this lengthy.

  • Two methods with different signatures, jquery is not calling correct method

    - by Lee
    There are two methods GetUserAssignedSystems() and GetUserAssignedSystems(string Id) These methods act very differently from each other. The problem is, when I want to call GetUserAssignedSystems(string Id), the parameter-less method is called. Here are the methods: [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems(string cacId) { return Data.UserManager.GetUserAssingedSystems(cacId); } [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems() { //do something else } Here is the jquery making the call: CallMfttService("ServiceLayer/UserManager.asmx/GetUserAssignedSystems", "{'cacId':'" + $('#EditUserCacId').val() + "'}", function(result) { for (var userSystem in result.d) { $('input[UserSystemID=' + result.d[userSystem] + ']').attr('checked', 'true'); } }); Any ideas why this method is being ignored?
