Is there any way to debug javascript in a web application? When I
develop JSP pages, and it has the javascript code in it. The problem is
the debugger in Java IDE (WSAD in my case) can only debug Java code but
not Javascript code.
When you write html or css then the validation proces is a good way of finding errors. I get some syntax error / code: 0 errors in IE, how can I figure out what the problem is. The thing is - it works - but it does not look good when IE says the page is done with errors...
I am trying to make a canvas element display an image with some text on using canvas.drawImage and canvas.fillText. Only problem is my code is generating a very odd and hard to debug error.
My work is putting in a large application that is basically split up between 30 or so Javascript files. I have some security concerns about this application.
Basic security concerns is:
1. Possible SQL injection and other forms of injection attacks on URLS of various server side components javascript accesses.
2. possible client side database access.
3. Incorrect use of http get for operations with possible side effects.
The security problems are probably relatively harmless. Mainly because the application should be running behind firewall.
However I would like to have an analysis tool that can go over the javascript code and allow me to see what urls are being called with what parameters.
Javascript that writes new javascript into page (so I can get all javascript files of application for analysis)
I know there are various javascript profilers and the like, anything out there that helps in the analysis of this kind of application?
I am writing a java application as a mozilla extension. Because mozilla uses javascript for the frontend, i need the javascript to call my external java application and pass one parameter to it.
IE 6.0 (not interested in other browsers at the moment)
I have looked everywhere I can find to look and googled until I am cross-eyed and am hoping somebody knows what I'm doing wrong.
I have an HTML application (.hta) working fine, except one thing. I'm trying to write to a local database from a .htm window (opened from the main .hta window) and it doesn't work with any of the combinations I've tried (and I admit to having tried a lot).
Here is one method I've tried:
strSQL = "Update myTable SET myField = 'myValue' WHERE myID = 12;" var db = new ActiveXObject("ADODB.Connection"); db.Provider = "Microsoft.Jet.OLEDB.4.0";0 db.ConnectionString = "Data Source='c:myDirectorymyDatabase.mdb'"; db.Open; db.execute(strSQL);
I can easily access the information in the myDatabase.mdb and display it on the screen.
I can ask for updated information to be input on the screen.
But stuffing that updated information back into the database is the problem.
Since I'm stuck in an .htm window, I don't have VBScript available, do I? If VBScript isn't available and it isn't physically possible with Javascript, then I'll have to revert to .hta windows, where I know I have VBScript available. But I'd rather do it all in Javascript within the .htm so as to avoid the security message that pops up when the .hta opens a new .hta. For various reasons I don't think it is possible for me to do this whole project within a single .hta.
I am trying to use the Goto method of the Word ActiveX object. I am trying to open a document and go to a named bookmark. If I use this code in VB it works, so I'm sure the approach is possible, I just can't get JavaScript to work with it.
Here is the code I am using, the error I get from IE is Object Expected: Hope someone can help! Any help would be much appreciated
function PageLoad() { var WordApp = new ActiveXObject('Word.Application'); WordApp.Visible = true; var documentlocation = crmForm.all.new_documentlocation.DataValue; var wd = WordApp.Documents.Open(documentlocation); wd.Select(); var Name = 'TestFred' var wr = wd.Selection.GoTo(What : Word.WdGoToItem.wdGoToBookmark,Name : 'TestFred'); }
I know this has to be easy, but I can't seem to figure it out. I'm debuggin' someone elses code...
x="hello"; +x+"world"
....and I don't get it! What does the "+x+"world" do? If I alert(x) the only thing that comes out is "hello". I also wondered why it doesn't error without the ";" at the end of the line.
I keep getting a syntax error on line 3 and 4 of this very simple script. Normally firebug would give me enough info to fix this but jQuery escapes me. I can see no reason for the errors. <script type="text/javascript"> $(".shipping-switch[name='shipping_switch']").click(function(){ var selector = "div#sub-address"; if($(this).val() === "1"){ $(selector).slideDown("fast"); } else { $(selector).slideUp("fast"); }}); </script>
I have to debug the error for eleave system for a company. when i do the testing i define that having an extra day for the service length at the system. i don't want you to settle the problem for me, just tell me where can i find the source to know where is the problem? at least i know where the souce it, so i can repair it.
I have a couple of problems with my site related to javascript
These areas of the site use jquery and they work fine in Firefox and Chrome but not in IE
First problem is related to tablesorter and pager (jquery plugins) that give a properly paginated list of members in Firefox but gives all the returned members in one big list using IE (and usually a complaint that 'this script is taking too long' as well)
The other problem is related to the member search age, it has these expandable areas where the user can select further search criteria - they use jquery 'slider' to reveal the collapsed areas, again this works fine in Firefox or Chrome but looks messy in IE
To compound the problem the only javascript debugger I have is a plugin for Firefox called Venkman which I find pretty useful to find problems with AJAX etc, but seeing as the jquery/javascript stuff works OK in Firefox it's difficult to fix what isn't wrong there!
So really, how do I go about even beginning to understand these problems so I can fix them?
what i want this to do is take the x_cityid and add it to teh hidden field with the id of citiesid (I will do an ajax call before this but my simple javascript is not working)what am i doing wrong?
function addtocitylist() { var x_cityid = document.getElementById('x_cityid'); var x_areaid = document.getElementById('x_areaid');
I have a piece of code that I dynamically load using globalEval(). But I am not able to debug this piece of code, specifically in IE, even when I place a "debugger;" statement.
I need to develope a multilanguage application in javascript: is there some particular library, or do you have some pointer to guidelines to follows: the messages should if possible be keeped in a separate file, one for language. Is there some standard format?
I having taken on a large project (set by myself), and I can never seem to plan out my functions, classes, variables etc... in a format that's easy to read, and follow.
Would anyone know of some kind of application which will allow me to "prototype" my application first? I am sure such a thing exists, I just don't know what I am looking for. I think I am after something along the lines of Microsoft Visio, but a bit simpler.
I know this sounds so stupid, but it's a project that I am working on. I need to develop an application where people can upload a picture of themself and then it will add a wig to their picture over their hair.I just don't know how the code scans the uploaded photo and finds where to add the wig to the picture. The program will be really simple. No choice of wigs there is just one wig and as soon as the picture is uploaded the wig should be added and then displayed.
