I'm working with ASP.Net MVC4 wiht view engine Razor. I like put mask date and time in TexBoxFor I installed for nugget jquery.maskedinput-1.3.min.js and add in the view
(document).ready(function () {
$("#FechaDen").mask("99/99/9999");
$("#HoraDen").mask("99:99:99");
});
But I have this error: Uncaught TypeError: Object [object Object] has no method 'mask'
How I can resolve this problem?
You seem to have forgotted to reference the jquery.maskedinput plugin in your page:
<script type="text/javascript" src="#Url.Content("~/scripts/jquery.maskedinput-1.3.min.js")"></script>
Make sure that the path is correct and that the plugin is actually situated in this folder. Use the Network tab of a javascript debugging tool such as FireBug to ensure that there are no 404 errors with your script references.
Also make sure that you have added this script inclusion after jQuery. Be careful because in the ASP.NET MVC 4 Internet Project Template, the ~/Views/Shared/_Layout.cshtml file renders jquery as a bundle at the end of the DOM:
#Scripts.Render("~/bundles/jquery")
#RenderSection("scripts", required: false)
</body>
So if you are putting this reference inside your view make sure that this happens inside the scripts section:
#section scripts {
<script type="text/javascript" src="#Url.Content("~/scripts/jquery.maskedinput-1.3.min.js")"></script>
<script type="text/javascript">
$("#FechaDen").mask("99/99/9999");
$("#HoraDen").mask("99:99:99");
</script>
}
Also notice that since this script is now at the end of the DOM I have gotten rid of the $(document).ready call which is no longer necessary (and which you got wrong in the code you have shown because you forgot to prefix it with a $).

I offen heard that loading jquery as last element is a good idea because this way a web page loads faster. At the same time I have a script in the header which shows error:
$(document).ready(function () {// Uncaught ReferenceError: $ is not defined
...
}
Should I move jquery loader before the script or I need to change this script some way?
Your concrete issue stems from the fact that you execute statements that use jQuery (i.e. they execute $, which is a function in the jQuery library, also called "the jQuery function" because jQuery is an alias) before it is loaded.
True, it is typically recommended to load scripts last, but that still means the scripts have to be loaded in the correct order, with usually jQuery before your own scripts using jQuery.
If you really want to load your own scripts before jQuery for some reason, you need to defer its execution and have a third helper script to run it, e.g.:
// script.js
(function() {
function myLibraryMainFn() {
$('div').text('simulating work, utilizing jQuery');
}
window.myNamespace = {
run: function() {
myLibraryMainFn()
}
};
}());
<!DOCTYPE html>
<html>
<body>
<div></div>
<script src="script.js"></script>
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
// Run your script now:
window.myNamespace.run();
</script>
</body>
</html>
Always refer library file first(in your case jQuery), then use it next..For page load and performance add it before body end tags of your HTML
I'm try to show 'addthis sharing' buttons when make ajax call. at the first call by ajax, buttons does not show, but when I reload whole page everything is OK, buttons is right place.
I searched a lots of fixes but no one works for me.
one of them is addthis.toolbox(); or window.addthis but when I use word addthis insde JavaScript tag, browser debugger writes error 'addthis is undefined'.
please give me smart advice what's happen and how can I fix it ?
Code (it's a partial view which load from ajax Call):
<script type="text/javascript" src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=ra-xxxxx" async="async"></script>
<div class="addthis_sharing_toolbox"></div>
<script>
addthis.toolbox(); // addthis - is undefined
</script>
I have fixed this problem.
In my project I have 3 View level
_layout
View
_partialview
I had addthis Js reference and button's Div inside the _partialView.
But when I move Js reference to View and change Url(add - &async=1) it works fine and now 'addthis' - is defined (till here is undefined).
Hare is full example:
View:
<script type="text/javascript" src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=ra-'yourPubId'&async=1"></script>
//Some Code
_partialView:
//Some Code
<div class="addthis_sharing_toolbox"></div>
<script>
$(function() {
addthis.init();
addthis.layers.refresh();
});
</script>
Good luck, everyone can use this perfect plugin 'addthis' when you load page by Ajax.
The async version of the addthis_widget.js script you're using was intended to be used for the newer dashboard tools, as the call to addthis.toolbox() is undefined because AddThis hasn't fully loaded yet. If you remove async="async" from the script, it should work.
Alternatively, you could add the async attribute this way:
<script src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=ra-xxxxx&async=1" type="text/javascript">
Then before you call addthis.toolbox(), make sure you call addthis.init().

I haven't used jQuery before, and I wanted to use DateTimePicker plugin on my web page.
I downloaded the plugin file and placed them in the same directory as the HTML files.
I directly applied the code at How to use it? in http://xdsoft.net/jqplugins/datetimepicker/.
It threw the following error.
Uncaught TypeError: undefined is not a function pixelcrawler:61 (anonymous function)
My code follows.
<script type='text/javascript' src="//ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="file:///jquery.datetimepicker.css"/ >
<script src="file:///jquery.datetimepicker.js"></script>
<script>
jQuery('#datetimepicker').datetimepicker();
</script>
<div class="container">
<div class="text-center">
<div class="page-header">
<h1>${conf['title']} <small>${conf['description']}</small></h1>
</div>
</div>
<div class="text">
<input id="datetimepicker" type="text" >
.
.
.
.
.
I could not figure out what the problem was. I have tried many other seemingly likely options, but it just did not work either.
(The ${} tags are used for the Mako template language. I am using Cherrypy.)
UPDATE:
I figured out the source of the problem.
It's from jQuery('#datetimepicker').datetimepicker();.
When tested, the datetimepicker() function was undefined. Maybe the way I imported the library was wrong?
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
I don't know your file-structure. I never include local files like this as I use relative URLs from the start rather than having to change everytime I'm ready to use the code, but it's likely one of the files isn't being loaded in. I've included the standard datepicker below using Google CDN's jQuery UI. Does your console log any resources not found?
I think your jQuery is loaded OK, because it's not telling you jQuery is not defined so it's one of your files.
BTW, PHP gets the home URL:
$home="http://" . $_SERVER['HTTP_HOST'].'/';
Demo code datepicker, jQuery UI:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
</script>
<input id="datetimepicker" type="text">
This is about the HTML parse mechanism.
The HTML parser will parse the HTML content from top to bottom. In your script logic,
jQuery('#datetimepicker')
will return an empty instance because the element has not loaded yet.
You can use
$(function(){ your code here });
or
$(document).ready(function(){ your code here });
to parse HTML element firstly, and then do your own script logics.
use jQuery.noConflict()
var j = jQuery.noConflict();
j(document).ready(function(){
j('#datetimepicker').datepicker();
})
For my situation, it was a naming conflict problem. Adding $J solves it.
//Old code:
function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
}
And the following is new code.
$j(function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$j("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
});
});
Hope it could help someone.
Usually when you get this problem, it happens because a script is trying to reference an element that doesn't exist yet while the page is loading.
As richie mentioned: "The HTML parser will parse the HTML content from top to bottom..."
So you can add your JavaScript references to the bottom of the HTML file. This will not only improve performance; it will also ensure that all elements referenced in your script files have already been loaded by the HTML parser.
So you could have something like this:
<html>
<head>
<!-- Style sheet references and CSS definitions -->
</head>
<body>
<!-- HTML markup and other page content -->
<!-- JavaScript references. You could include jQuery here as well and do all your scripting here. -->
</body>
</html>
You may see if you are not loading jQuery twice somehow. Especially after your plugin JavaScript file loaded.
I has the same error and found that one of my external PHP files was loading jQuery again.
The issue because of not loading jquery ui library.
https://code.jquery.com/ui/1.11.4/jquery-ui.js - CDN source file
Call above path in your file.
And if you have this problem in slider or slideshow you must use jquery.easing.1.3:
<script src="http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js"></script>
I had trouble getting selectable to work with ASP.NET. It turns out I wasn't properly including everything, but this gentleman made it foolproof: Three steps to use jQuery UI in ASP.NET MVC 5.
I don't think jQuery itself includes datetimepicker. You must use jQuery UI instead (src="jquery.ui").
I'm very new to JavaScript (just started a few hours ago and trying to get a script working). I went through a few tutorials on W3 and the 'hello world' code works when I paste it directly into my HTML but I'm having a problem with a script (I've had problems with other scripts as well but I am not sure what I'm doing wrong).
I have this code that I want to test in my HTML, I copied the HTML in and it looks the same then I made a file in my static folder called edit.js and copied the JavaScript into it (exactly as shown). It didn't work no errors on the page but when I click it nothing happens. I tried to paste a W3 'hello world' code in and that worked but this script does not.
I tried to inspect the code in Chrome and that's where I see the above error (under the resources tab). I can open the js file using Chrome which makes me think the js file is accessible and pointing correctly but I'm not sure how to get it working. I'm using Jinja2 as my template engine to render the HTML and in my header I have:
<script language="JavaScript" type="text/javascript" src="static/edit.js"></script>
and in my main template (the one that gets rendered on all pages) I have:
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
edit.js:
(even putting it within the script tag directly on the page I want to use it on doesn't work)
$('#editvalue').click(function(e){$('#storedvalue').hide();$('#altervalue').show();});
$('#savevalue').click(function(e){
var showNew = $('#changevalue').val();
$('#altervalue').hide();
$('#storedvalue').show();
$('#storedvalue span').text(showNew);
});
HTML:
(it's embedded in a larger page)
<head>
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script language="JavaScript" type="text/javascript" src="static/edit.js"></script>
</head>
... my html code..
<div id="wrapper">
<div id="container">
<div id="storedvalue"><span>Hello</span> [edit]</div>
<div id="altervalue" style="display:none;"><input type="text" name="changevalue" id="changevalue" value="Hello"> [save]</div>
</div>
</div>
I have never been able to successfully run a JavaScript that wasn't on W3 yet. I get the same problem with other scripts even though I see people online saying they work fine for them. Do I need to do anything extra to make this work?
My two questions are:
What am I doing wrong?
Because Javascript seems to just not work when there's a problem, is there a way to get errors or information on what's actually wrong?
I read Uncaught ReferenceError: $ is not defined? and have been trying to figure this out for the last hour and can't see my problem.
First you need to place the jQuery script tag first.
Second, you need to do one of the following things:
Put your code within this function:
$(document).ready(function(){/*CODE HERE*/});
Or like this:
$(function(){
/*CODE HERE*/
});
The DOM needs to be ready before you can use it. Placing your code within anonymous functions that are executed on the ready event of the DOM is how you can do this.
Edit:
$(function(){
$('#editvalue').click(function(e){$('#storedvalue').hide();$('#altervalue').show();});
$('#savevalue').click(function(e){
var showNew = $('#changevalue').val();
$('#altervalue').hide();
$('#storedvalue').show();
$('#storedvalue span').text(showNew);
});
});
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
Script tag for jQuery should come before your custom javascript.
Follow by edit.js
<script type="text/javascript" src="static/edit.js"></script>
Try removing the language attribute..sometimes work for me. It's obsolete now .. i think
You need to include jquery before you can use it.
I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio:
Microsoft JScript runtime error: 'this.node' is null or not an object
and it point to some function inside the JavaScript like
this.node.onload=function(){..............//I am not a java guy so do not know much about this
Where am I going wrong? Why does the site compile correctly but throw this runtime error?
I also tried inserting this java code inside the master file in the <head>, but same error. This is urgent please so if someone experienced can pinpoint where exactly to put the code that would be solve my problem quickly.
Have you included a reference to the jQuery library? A good practice would be to have the jQuery include in the Master.
<head>
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js">
</script>
<!-- the remainder of your .js references should follow-->
</head>
If it's your intention to have that script run on 'page load', then ensure you have it set correctly:
$(document).ready(function() {
// put all your jQuery goodness in here.
});
More info on jQuery document ready.
I'm not sure exactly what it is you are doing with that snippet of code, but I don't think it is the proper syntax.
You probably should re-write it to look like this:
$(document).ready(
function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
Just passing in the function to the jQuery selector will probably get some wonkiness.
Thank you everyone! there was no problem with either the syntax in the javascript or the location/page where it was first included by me. I just figured out that the mistake was somewhere else. This javascript works on an <img> tag. It zooms the image insdie the <img> tag. I was using the <asp:ImageButton> instead og <img>. It works perfect as soon as I replaced it. Thank you all for your time and the knowledge sharing.
