Angular-UI Tabs: Add Class To A Specific Tab


Answer :

I'm not sure that you can apply ng-class to tabs like that. After trying and failing I decided to look at the bootstrap-ui source for tabs and made an interesting discovery related to the tab heading attribute. Apparently you can put html in the heading section if you place the tab-heading as a child to a tab element.

Check out the tabheading directive in here.

This is the example they show:

<tabset>   <tab>     <tab-heading><b>HTML</b> in my titles?!</tab-heading>     And some content, too!   </tab>   <tab>     <tab-heading><i class="icon-heart"></i> Icon heading?!?</tab-heading>     That's right.   </tab> </tabset>

In your case I think you might be able to do something like this to get the same effect:

<tab ng-repeat="tab in tabs" active="tab.active">     <tab-heading>{{tab.title}} <span ng-show="tab.new">new</span></tab-heading>     <div ng-include="tab.page"></div> </tab>

@TyndieRock is right that you can't, as far as I'm aware, apply classes to bootstrap-ui tabs. Any ng-class is stripped and directly adding a class causes bad behavior and it blocks any attempt to inject into it.

I did see an issue posted on github asking for custom css support. So maybe someday.

@TyndieRock's solution gets you closer but doesn't get you all the way. Kudos for finding tab-heading. Although his syntax is just slightly off.

Here's what I think you'd want:

 <tabset>     <tab ng-repeat="tab in tabs">     <tab-heading ng-class="{new:tab.new}">{{tab.title}}</tab-heading>         <div ng-include="tab.page"></div>     </tab> </tabset>

This will let style the text. But it doesn't work so well for your css content.

You might want to do your own custom tabs. It is a hassle but that'll give you the control you're looking for.


This issue was driving me mad, so here is what i did to have custom tab heading styling. Works for Angular >= 1.1.5 as it is the only one to have ternary operator in expressions.

One needs to target the <tab> element and not tab heading. Unfortunatelly ng-class will not work and get mangled together with other ng-class directives from the templates.

If you try to target the tab heading element you will find that there is not much you can do with it. There are no parent selectors in CSS so there is no way to reach that anchor tag where most of the action is going on.

So to have the cookie and eat it: 1) have your styles target descending anchor tag that gets generated by bootstrap tab directive

2) apply the class using this obscure syntax:

 <tabset>         <tab class="{{orderForm.detailsForm.$invalid ? 'invalid-tab' : 'valid-tab'}}">             <div>CONTENT</div> </tab> </tabset>

Then it all works as expected and proper classes are added to the <li> that is a parent to the interesting <a> tag.

To sum up: When ng-class is misbehaving and has interpolation issues, try to be more direct.

hope that helps someone.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
