javascript - function to define current class in js -


What I want to do is a function that defines a "current" class for "code"; Li & gt; The tag depends on the page name. For example, if the name of the page is index.php, then I have to decide whether and

  • I am sorry that I am not the best by explaining it. Here is an example code & lt; Ul id = "navigation" & gt; & Lt; Li & gt; & Lt; A href = "index.php" & gt; & Lt; / Li & gt; & Lt; / Ul & gt;

    I want the class to be "on" to & lt; Li & gt; tag, if the link is similar to the page name, is there any way to do this? Or am I on a waste mission?

    • I think what you are asking, do you want to change this to the current page of the link Pointing here what the code looks like. 

      var list = document.getElementsByTagName ('a'); Var page = window.location.pathname; Var i = list.length; While (i -) {if (list [i] .src.indexOf (page)> gt; {list [i] .className = 'current'; }}

    Note that this is not a very accurate method, the basic structure is correct, but for example a link somewebsite.com is actually pointing to somewebsite.com/index.php is. Therefore, it can cause a problem on the home page based on the link. Also, how it determines how your links are set up, you probably have to go to the purse page variable. This will return something like /help/faq/foo.php while the page can only have a link to faq / foo.php. It all depends on the setup of your site, so I will leave it for you to tweak for .

    I added more details since the posting, so I thought I would need to make you a list & lt; Li & gt; > All of the links in the tag in the page & lt; A & gt; is not a tag.

    Eclipse CDT variable colors in editor -

    I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
