  • JavaScript using toString on a Function object to read text content

    - by mseeley
    Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

  • using respond_to format.js to replace the content of a textarea on rails

    - by Stacia
    I have some saved text in my create controller. If it's not stressful, I'd like it to populate a textarea on the page with the saved text along with displaying the error message fields (which is what's already happening). I've used things like replace_html before, but I don't know if there's an easy way to get to textarea or text field IDs and just replace the value of the text. For now I'm just going to do some javascript but it would be nice to know the rails shortcut. edit: I wasn't in the right mindset because this app uses extjs and was trying to figure out how to do it this way. The text box is actually an ext status bar (same as here : http://www.extjs.com/deploy/dev/examples/statusbar/statusbar-demo.html ) which doesn't get created until the page is finished loading. When I try to enter commnands like the first poster suggested, I get "setvalue is not a function". Playing with firebug on the page I can get it to set the value after loading by using (whatever method to get it through ext or scriptaculous).value = "lol" but none of the page update things work with this.

  • Free server solution for strict content photos with geotags

    - by Max Gontar
    Hi! I would like to create some kind of open free "group" posting of photos with geotags First I thought about Panoramio, but seems there is no API for photos upload. By now I can see only two ways: Flickr - there are groups but you have to approve group membership anyway, or use tags for grouping which is bad for maintenance Custom server solution which will cost efforts and hosting Can you suggest other free photo services with geotags functionality, or opensource solutions? Thank you!

Is there a way of selecting the correct node from those values?

  • Customize link for add content

    - by Chetan
    When I have a custom node type and I want to create a page, can the link be something other than what Drupal automatically assigns? i.e. Currently to add a node-type it is: www.example.com/node/add/node-type but can it be customized to just www.example.com/node-type ?

  • Using content from the project in tests

    - by oillio
    I am working with Visual Studio 2010 and it's integrated testing functionality. I have an XML file in my project which is set to copy to the output directory. I can access the file just fine when I compile and run the project. But it doesn't exist when I attempt to access it within a TestMethod. It looks like the test is run with the working directory set to an "Out" directory created within the TestResults directory. I can set a breakpoint before I use the file. If I then copy the file into this "Out" directory and continue running the test it accesses the file properly. But that is not really how I want my automated tests to function. Is it possible to tell VS to copy the build directory into this working directory?

  • WPF WebBrowser - How to Zoom Content?

    - by Beems
    Trying to test basic browser concepts in a WPF (C#/XAML, .NET 4.0) WebBrowser application. So far, the only problem is programatically zooming. Has anyone had any experience with this? MSDN lists nothing: http://msdn.microsoft.com/en-us/library/system.windows.controls.webbrowser.aspx Additionally, I have tried various things such as RenderTransform options to no avail. Either this is not possible or not documented. I'm hoping for the latter. Note that a WinForm solution isn't acceptable. Thanks in advance for any help, Beems

  • Keeping User-Input UITextVIew Content Constrained to Its Own Frame

    - by siglesias
    Trying to create a large textbox of fixed size. This problem is very similar to the 140 character constraint problem, but instead of stopping typing at 140 characters, I want to stop typing when the edge of the textView's frame is reached, instead of extending below into the abyss. Here is what I've got for the delegate method. Seems to always be off by a little bit. Any thoughts? - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { BOOL edgeBump = NO; CGSize constraint = textView.frame.size; CGSize size = [[textView.text stringByAppendingString:text] sizeWithFont:textView.font constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; CGFloat height = size.height; if (height > textView.frame.size.height) { edgeBump = YES; } if([text isEqualToString:@"\b"]){ return YES; } else if(edgeBump){ NSLog(@"EDGEBUMP!"); return NO; } return YES; } EDIT: As per Max's suggestion below, here is the code that works: - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { CGSize constraint = textView.frame.size; NSString *whatWasThereBefore = textView.text; textView.text = [textView.text stringByReplacingCharactersInRange:range withString:text]; if (textView.contentSize.height >= constraint.height) { textView.text = whatWasThereBefore; } return NO; }

  • JQGrid: Dynamically set a cell to uneditable based on content

    - by Shawn
    I'm having some issues getting some cells (with cellEdit: true) to be non-editable even though the column is set to editable. I've tried many ways, like beforeEditCell, formatters, etc. None seem to work. The closest I've got is by setting a formatter to the column that I'd like to be editable and then using setCell to set the 'not-editable-cell' class (snippet below). The first time you click the cell, it unfortunately goes into edit mode, but if you click elsewhere and try to re-edit the cell, it's successfully uneditable. I've also tried using the same snipped but inside of beforeEditCell, it successfully stops the cell from being edited but in turn 'freezes' the grid. You can no longer select any other cell. function noEditFormatter(cellValue, options, rowObject) { if (cellValue == 'test') jQuery("#grid").jqGrid('setCell', options.rowId, 'ColName', '', 'not-editable-cell'); return cellValue; } Any help would be much appreciated.

  • How to get ListView to grow to the size of content

    - by Jared
    So I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use? I'm open to any ideas. I really just don't know how to go about this. Thanks

  • Echoing variable construct instead of content

    - by danp
    I'm merging two different versions of a translations array. The more recent version has a lot of changes, over several thousand lines of code. To do this, I loaded and evaluated the new file (which uses the same structure and key names), then loaded and evaluated the older version, overwriting the new untranslated values in the array with the values we already have translated. So far so good! However, I want to be able to echo out the constructor for this new merged array so I can cut and paste it into the new translation file, and have job done (apart from completing the rest of the translations..). The code looks like this (lots of different keys, not just index): $lang["index"]["chart1_label1"] = "Subscribed"; $lang["index"]["chart1_label2"] = "Unsubscribed"; And the old.. $lang["index"]["chart1_label1"] = "Subscrito"; $lang["index"]["chart1_label2"] = "Não subscrito"; After loading the two files, I end up with a merged $lang array, which I then want to echo out in the same form, so it can be used by the project. However, when I do something like this.. foreach ($lang as $key => $value) { if (is_array($value)) { foreach ($value as $key2 => $value2) { echo "$lang['".$key."']"; // ... etc etc } } } ..obviously I get "ArrayIndex" etc etc instead of "$lang". How to echo out $lang without it being evaluated..? Once this is working, can add in the rest of the brackets etc (I realise they are missing), but just want to make this part work first. If there's a better way to do this, all ears too! Thanks.

  • WPF DataGrid content does not scroll

    - by muffd
    After searching for a fix to this issue in the previous answers I've decided to post my example. I have the following situation: my datagrid is placed inside a Grid row that is itself placed inside a UserControl.The UserControls does not have a fixed height, as I want the control to resize together with the window. The datagrid is bound to a datasource. Needless to say that the Datagrid itself and its container(the Grid) do not have set a fixed height. My question is: how do I make the vertical scrollbar of the DataGrid to appear?

  • Centre content vertically in a <div>

    - by Ben
    Hi, this is probably very simple to do, but I can't quite get it right. I have a <div> which contains two <a> tags. I would like the <a> tags to be both centred vertically and horizontally. I have set them to centre horizontally by setting the text-align:center; on the div, but can't figure out how to vertically centre them. How would I go about doing this? Thanks.

  • JS DOM: Get elements by text content.

    - by hristo
    Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

  • UIWebview isn't displaying content I want it to display

    - by Knodel
    In my app I have a UIWebView which loads different rtf files. I use this function to load these files: - (void)loadFile:(NSString*)file { NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* sourceFilePath = [resourcePath stringByAppendingPathComponent:file]; NSURL* url = [NSURL fileURLWithPath:sourceFilePath isDirectory:NO]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [webview loadRequest:request]; } The UIWebView displays nothing. When I enter the debugger, the file string value is which I need, but resourcePath and sourceFilePath values are "nil". What am I doing wrong? Thanks in advance!

  • jQuery focus on content of input / textarea - not working properly in IE8

    - by katebp
    I want the input fields on my site to select all the text when the user first clicks on them, but in IE8 the text is selected for a split second then reverts back to normal. Works fine in FF. My js code: $(document).ready(function () { //HTML DOM document is ready // Add this behavior to all text fields $("input[type='text'], textarea").live("focus", function(){ // Select field contents this.focus(); }); }); Any ideas? I've tried adding ".select()" after "this" and bizarrely enough it works, but throws loads of js errors in FF and IE. Thanks

    - by dana
    i'm trying to save 100 caracters form user in a 'microblog' minimal application. my code seems to not have any mystakes, but doesn't work. the mistake is in views.py, i can't save the foreign key to user table models.py looks like this: class NewManager(models.Manager): def create_post(self, post, username): new = self.model(post=post, created_by=username) new.save() return new class New(models.Model): post = models.CharField(max_length=120) date = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, blank=True) objects = NewManager() class NewForm(ModelForm): class Meta: model = New fields = ['post'] # widgets = {'post': Textarea(attrs={'cols': 80, 'rows': 20}) def save_new(request): if request.method == 'POST': created_by = User.objects.get(created_by = user) date = request.POST.get('date', '') post = request.POST.get('post', '') new_obj = New(post=post, date=date, created_by=created_by) new_obj.save() return HttpResponseRedirect('/') else: form = NewForm() return render_to_response('news/new_form.html', {'form': form},context_instance=RequestContext(request)) i didn't mention imports here - they're done right, anyway. my mistake is in views.py, when i try to save it says: local variable 'created_by' referenced before assignment it i put created_py as a parameter, the save needs more parameters... it is really weird help please!!

  • Print UITableView that has content off screen?

  • How to use JQuery to remove dynamic content?

    - by ed.talmadge
    I have an html page that is generated by a CMS. I cannot modify the page, but can add JavaScript. Each time the page loads, a JavaScript function (that I cannot modify) dynamically inserts a paragraph onto the page. How can I use JQuery to .remove() that paragraph whenever it is loaded? For example, when the page first loads, it look like this (blank): <div></div> Then, a few seconds later, a JavaScript function (that I have no control over) adds a paragraph to the page. The page then looks like this: <div><p id="foo">bar</p></div> How can I use JQuery to remove the paragraph with id=foo each time it is dynamically loaded onto the page?
