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

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

(JavaScript) Show preloader message when page is unloading - housecor

This works cross browser. Merely using onclick on a submit button to show a preloader/ please wait dialog doesn't work in IE since it doesn't show images once the page is being unloaded.

Be sure to call the exact version desired or the script is only cached for one hour! http://encosia.com/2009/10/11/do-you-know-about-this-undocumented-google-cdn-feature/

Pass as many arguments as you wish. You can access them in the arguments array.

(JavaScript) Default parameters - housecor

This sets b to 3 if b isn\'t passed. So all params all optional.

(JavaScript) Javascript scope - housecor

Thu, 23 Sep 2010 05:01:56 UTC

There are two scopes in JavaScript: global and function. If you don\'t declare a variable (using var), it assumes global. \r\n\r\nVariables declared in functions have function scope.

(JavaScript) Enforce maxlength for all textareas on page - housecor

Just be sure to slap the div for the chars left message within the same div/p as the textarea so the dom walk works.
