cross site - Use jQuery to check if a URL on another domain is 404 or not? -

-

On the client side using JQuery, I want to know if I can only check if a link URL is valid or not (i.e., T 404 comes back). This link points to another domain, so if I only use $ .get (), then the permission problem ends with me. I remember reading something about using a JSONP request, but I do not remember.

I found a solution that looks like (using YQL): 

  $ GetJSON ("http://query.yahooapis.com/v1/public/yql?" + "Q = Select% 20 *% 20from% 20html% 20where% 20url% 3D% 22" + encodeurIComponent (url) + "% 22 And format = xml 'and callback =? ", Function (data) {if (data.results [0]) {// do anything}});

The url you want to see is in the variable 'url'.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
