  • What regular expression do I need to check for some non-latin characters?

    - by zeckdude
    I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

  • Javascript check of a form, not waiting for ajax response

    - by Y.G.J
    this is a part of the check in my form function check(theform) { var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.username.value)) { alert("not valid username"); theform.username.focus(); return false; } $.ajax({ type: "POST", url: "username.asp", data: "username="+theform.username.value, success: function(msg){ username = msg; if (!username) { alert("username already in use"); return false; } } }); var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.password.value)) { alert("not valid password"); theform.password.focus(); return false; } } for some reason of sync... it check the username then duplicated username with the ajax and not waiting for respond and jump to the password check. i don't want to insert the rest of the code to isreadystate (or what ever it is) because i might move the username duplicate check to the end... and then the function will end before the ajax anyway what should i do?

  • whats faster, more efficient, loading a js file with arrays or populating arrays from tables

    - by Leigh
    I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

  • Work time in fullcalendar [Solution]

    - by Zozo
    Full calendar have no included options to work-time feature (selecting first and last rows in agenda view for any day - where in example company is not working). I managed something like that: viewDisplay: function(view){ $.ajax({ url: 'index.php?r=calendar/Default/worktime', dataType: 'json', success: function(data){ if(view.name=='agendaWeek') selectWorkTime(data, 30, 0, 24, false); else if(view.name=='agendaDay') selectDayWorkTime(data, 30, 0, 24, view, false); } }); } Where index.php?r=calendar/Default/worktime is php file returning json. It looks like that: $arr = array( 'mon' => array('8:00', '17:00'), 'tue' => array('9:00', '15:00'), 'wed' => array('9:30', '19:00'), 'thu' => array('6:00', '14:00'), 'fri' => array('0:00', '24:00'), 'sat' => array('9:00', '14:00'), 'sun' => array() ); foreach ($arr as &$day){ foreach($day as &$hour){ $tmp = explode(':', $hour); $hour = $tmp[0] * 3600 + $tmp[1] * 60; } } print json_encode($arr); and at the end, some functions using for counting and selecting work-time: function selectDayWorkTime(timeArray, slotMinutes, minTime, maxTime, viewObject, showAtHolidays){ var dayname; $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.fc-work-time').remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); switch(viewObject.start.getDay()){ case 1: dayname='mon'; break; case 2: dayname='tue'; break; case 3: dayname='wed'; break; case 4: dayname='thu'; break; case 5: dayname='fri'; break; case 6: dayname='sat'; break; case 0: dayname='sun'; break; } for(var day in timeArray){ if(day == dayname){ if($('.fc-content').find('.fc-view-agendaDay').find('.fc-'+day).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; for(startBefore; startBefore < endBefore; startBefore++){ $('.fc-view-agendaDay').find('.fc-slot'+startBefore).find('div').addClass('fc-work-time-day'); } for(startAfter; startAfter <= endAfter; startAfter++){ $('.fc-view-agendaDay').find('.fc-slot'+startAfter).find('div').addClass('fc-work-time-day'); } } } } } function selectWorkTime(timeArray, slotMinutes, minTime, maxTime, showAtHolidays){ for(var day in timeArray){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; if(startBefore > endBefore) endBefore = startBefore; if(startAfter > endAfter) startAfter = endAfter; try{ selectCell(startBefore, endBefore, 'fc-'+day, 'fc-work-time', false, showAtHolidays); selectCell(startAfter, endAfter, 'fc-'+day, 'fc-work-time', true, showAtHolidays); } catch(e){ continue; } } } function selectCell(startRowNo, endRowNo, collClass, cellClass, closeGap, showAtHolidays){ $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.'+cellClass+''+startRowNo+''+collClass).remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); if($('.fc-content').find('.fc-view-agendaWeek').find('.'+collClass).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var width = $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').width(); var height = 0; if(closeGap && (startRowNo != endRowNo)){ height = $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).height(); } $('.fc-view-agendaWeek').find('.fc-agenda-body').prepend('<div class="'+cellClass+' ' + ''+cellClass+''+startRowNo+''+collClass+'"></div>'); $('.'+cellClass).width(width - 2); height += $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ endRowNo).position().top - $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top; $('.'+cellClass+''+startRowNo+''+collClass).height(height); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-top', $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-left', $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').offset().left - width / 2); } } Don't forget about CSS: .fc-work-time-day{ background-color: yellow; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } .fc-work-time{ position: absolute; background-color: yellow; z-index:10; margin: 0; padding: 0; text-align: left; z-index: 0; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } So, I've got some questions about - is the other way to make the same, but no using absolute div's in agendaWeek? And... How can I get in viewDisplay function actual slotMinutes, minTime and maxTime

  • Problem Render backbone collection using Mustache template

    - by RameshVel
    I am quite new to backbone js and Mustache. I am trying to load the backbone collection (Object array) on page load from rails json object to save the extra call . I am having troubles rendering the backbone collection using mustache template. My model & collection are var Item = Backbone.Model.extend({ }); App.Collections.Items= Backbone.Collection.extend({ model: Item, url: '/items' }); and view App.Views.Index = Backbone.View.extend({ el : '#itemList', initialize: function() { this.render(); }, render: function() { $(this.el).html(Mustache.to_html(JST.item_template(),this.collection )); //var test = {name:"test",price:100}; //$(this.el).html(Mustache.to_html(JST.item_template(),test )); } }); In the above view render, i can able to render the single model (commented test obeject), but not the collections. I am totally struck here, i have tried with both underscore templating & mustache but no luck. And this is the Template <li> <div> <div style="float: left; width: 70px"> <a href="#"> <img class="thumbnail" src="http://placehold.it/60x60" alt=""> </a> </div> <div style="float: right; width: 292px"> <h4> {{name}} <span class="price">Rs {{price}}</span></h4> </div> </div> </li> and my object array kind of looks like this

  • Google Maps and Json structure

    - by mark
    I found a great script to plot markers on Google Maps. It uses an Json file to laod it. The problem is I don't know what the structure looks like in this case. Can you help? function loadMarkers() { var bounds = map.getBounds(); var zoomLevel = map.getZoom(); $.post("/gmaps/markers/index.php", {zoom: zoomLevel, swLat: bounds.getSouthWest().lat(), swLon: bounds.getSouthWest().lng(), neLat: bounds.getNorthEast().lat(), neLon: bounds.getNorthEast().lng()}, function(data) { processMarkers(data, _smallMarkerSize); }, "json" ); } function processMarkers(webcams, markerSize) { var marker = null; var markersInView = new Array(); var idsInView = new Array(); // Loop through the new webcams for (var i = 0; i < webcams.length; i++) { var idx = markers.indexOf(webcams[i].id); if (idx == -1) { var info_html = "<table class='infowindow'>"; info_html += "<tr><td class='img'>"; info_html += "<img src='" + webcams[i].smallimg + "' /><td>"; info_html += "<td><p><b>" + webcams[i].loc + "</b>"; info_html += "<br /><a href='/webcam/" + webcams[i].url + "' target='_blank'>Show webcam</a></p></td></tr>"; info_html += "</table>"; marker = new WebcamMarker(new GLatLng(webcams[i].latitude, webcams[i].longitude), {image: "" + webcams[i].smallimg + "", height: markerSize, width: markerSize}); marker.myhtml = info_html; map.addOverlay(marker); markersInView[webcams[i].id] = marker; } else { markersInView[webcams[i].id] = markers[webcams[i].id]; } idsInView.push(webcams[i].id); } // Now remove the markers outside of the viewport for (var i = 0; i < webcamids.length; i++) { var idx = markersInView.indexOf(webcamids[i]); if (idx == -1) { marker = markers[webcamids[i]]; map.removeOverlay(marker); } } markers = markersInView; webcamids = idsInView; }

  • Ajax, php, mysql not working mysql limit

    - by Hofmeister Ákos
    I have 3 files. list.php $articles = $mysqli->query("SELECT mainPictureBig, title, writer, writeDate, link FROM articles WHERE category=$this->category ORDER BY writeDate DESC LIMIT 0,10"); while($article = mysqli_fetch_row($articles)) { echo "<a href=\"".$this->url."/".$article[3]."/".$article[4]."\"><div id=\"listElement\"> <div id=\"listElementWallpaper\" style=\"background-image: url('category/img.jpg');\"></div> <div id=\"listElementContent\"><div id=\"listElementTitle\">".$article[1]."</div>".$this->giveWriter($article[2]).", ".$this->giveDate($article[3])."</div> </div></a>"; } $maximumElements=ceil($numberOfContent / 10) * 10; It's working, so there is no problem, it lists the first 10 elements from the sql table, and i got the $numberOfCOntent part also. Than i have a button: echo "<div id=\"listMore\"><div id=\"buttonOne\" onclick=\"listMore($this->category,$maximumElements)\">Load more</div></div>"; There is also no problem, i load the .js file, and it looks like: var from = 10; function listMore(categoryId, maximum) { $( "#listMore" ).slideUp( 200, function() { $( "#listMore" ).html("<center>Loading..</center>"); $( "#listMore" ).slideDown( 500, function() { $.post( "http://localhost/ajax.php", {type: "listMore", id: categoryId, sqlFrom: from} ) .done(function( elements ) { $("#listBody").append( elements ); if(maximum > from+10) { from = from+10; $( "#listMore" ).slideUp(200, function() { $( "#listMore" ).html("<div id=\"buttonOne\" onclick=\"listMore("+categoryId+","+maximum+")\">Load more</div>"); $( "#listMore" ).slideDown(200); }); } else $( "#listMore" ).slideUp(200); }); }); }); } And it's also working, and the problem is in the PHP file. As you can see, i'm sending an integer the "from" variable, the PHP file: $articles = $mysqli->query("SELECT mainPictureBig, title, writer, writeDate, link FROM articles WHERE category=$id ORDER BY writeDate DESC LIMIT $from,10"); It's also working, but not loading the next 10, only the next 9. So it skips the very next row and loads the rows only after the very first, so only 9. I tried to write here only the important part of the code, so i skipped some echo part etc. Any idea?

  • Return highest number found in an array of strings

    - by Mdd
    I have an array of objects. The objects have a property called level that is a string which contains a number and is in consistent format. I am trying to find the highest number and return just that one but I seem to be blocked as far as how to proceed from my current code. Here is a fiddle to my current code: http://jsfiddle.net/6sXYR/ Here is my JavaScript: var myArray = [ { color: 'blue', level: 'L1' }, { color: 'red', level: 'L1' }, { color: 'green', level: 'L2' }, { color: 'yellow', level: 'L2' }, { color: 'purple', level: 'L3' } ]; for (var i = 0; i < myArray.length; i++) { console.log( myArray[i].level.substring(1,2) ); }; The result I am trying to get is to return just the number '3' from the example above. The highest number may not always be in the last object in the array, but it will always be in the format of L#.

    I have the following script: http://jsfiddle.net/oshirowanen/6SUwR/3/ How do I give the drop down section a dynamic width based on the characters in the dropdown? For example, if "navigation 1" was "this is the first item in the navigation", How do I make the width of the whole dropdown wider automatically, but without affecting the size of the navigation button which causes the dropdown the dropdown when mouseover'ed? Basically, I don't want to text to wrap in the dropdown, but at the same time, I don't want to button for the dropdown to go wider.

  • Swapping content in a seperate div on hover

    - by Fuego DeBassi
    I feel like this should work: $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); Basically I am hiding all the .children of "#viewport on load, then when a seperate element is hovered, in this case .module .one I want to change something on the corresponding viewport ID #viewport #one. Basic idea is a variable content window, where when a thumbnail or whatever I put in the modules swaps the content shown in the viewport. Something I am doing wrong? Here is my full code: <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $("#viewport").children().hide(); $(".module").hover(function() { $(this).find(".caption").slideDown().end().siblings('.module').addClass('under'); },function() { $(this).find(".caption").slideUp().end().siblings('.module').removeClass('under'); }); $(".module .one").hover(function() { $("#viewport #one").addClass('red'); }); }); </script> The bigger hover function in the middle is for some fancy rollover effects that the modules will perform themselves, but for these purposes I just want to figure out why I can't add a Class to a separate element when another is hovered. Would love some help/advice!
