Jquery – String manipulation in jQuery

jquerystring

I have a div which collapses clicking on a text header. I want to change the header from "+ filters" to "- filters" accordingly (when the div is collapsed or expanded)

How can I perform this with jQuery?

if (headerDiv.text() starts with "+")
    replace "+" with "-" 
else 
    replace "-" with "+"

Never mind, I figured it out

if ($(header).text().trim().charAt(0) == "+")
    $(header).text($(header).text().replace("+", "-"));
else
    $(header).text($(header).text().replace("-", "+"));

If this is not the correct way, I'd appreciate a heads up

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

Javascript – How to detect a click outside an element

Note: Using stopPropagation is something that should be avoided as it breaks normal event flow in the DOM. See this CSS Tricks article for more information. Consider using this method instead.

Attach a click event to the document body which closes the window. Attach a separate click event to the container which stops propagation to the document body.

$(window).click(function() {
  //Hide the menus if visible
});

$('#menucontainer').click(function(event){
  event.stopPropagation();
});
