(JavaScript) Access server side C# variabes in javascript - housecor

Fri, 08 Apr 2011 01:51:18 UTC

Options: 1. Write the desired values into a hidden field that contains json. Reference the hidden field by ID and parse the json to get the desired vars. 2. Call a webmethod that returns the values in json format 3. Write js via the code-behind that writes the variables to the page in a separate script tag. The js is placed inline in the page. Call: Page.ClientScript.RegisterClientScriptBlock. See example below. So why is putting the entire javasscript in a string within the code-behind a lousy idea? 1. No code coloring 2. No syntax checking 3. Have to escape quotes which makes it hard to read and adds work 4. JS isn't cached since it's a string sitting within the html, unlike an attached .js file. 5. No separation of concerns. Client script should ideally be in a .js file to keep server side business logic from being intermingled with other concerns. 6. Inability to reuse. A useful .js file can be called from multiple pages. js stored in a string of a code-behind is page specific. 7. No IDE assistance for formatting or intellisense support

(C#) Add js and css from codebehind - housecor

(jQuery) jQuery event delegation - housecor

Thu, 17 Mar 2011 06:00:46 UTC

Note that this is more efficient than binding an event to every individual TD. Plus, as a bonus, any new TD's added are bound with this method. When using event delegation you can add as many matching elements to the DOM as you like after the event is bound and they work too. e holds a reference to the element that was clicked.
