jquery live automatically incrementing keyup event -


I'm really confused, and it's also not sure what to look for in finding answers. I'm getting many calls for the javascript function I'm not able to understand.

What does this code do 

  $ ('expenses_txt'). Live (\ 'keyup \', function () {$ (this) .typeWatch ({Highlight: true, wait: 500, capture lendement: 0, callback: Calculate_expenses});});

"calculate_expenses" is a JavaScript function that uses jquery ajax to call a php page which gives data appearing in a span.

I'm using firebug to help me debug and in the Calculate_expenses function, when I'm calling this function, I've put "console.log" to debug it.

This is happening when this happens, so I have only 1 input box, when I press only one key, puts the output given in the console as a debug msg, as it should, When I press an input again in the same input box the console is doubled (i.e., the calculate_expenses function was called twice, but it should be called only once), when I press a key again (total 3 Key press) Output in the console The calculate_expenses function now ..... and even further. I do not really know what is happening here in the code that I see that it will call only the CalText Expense function at 1 time, but when the firebug is used, it is actually being called and called. When i do not want it

Any thoughts? Am I using it () If I use the "key usage" event it works fine, to type the problem I need to use the plug-in typingweb plug-ins, until the typing process ends and the trigger also triggers the event. Get ready soon The reason I am using Live () is because I add element to DOM dynamically and this is the only way, I could understand how to use both types and dynamically add those components to the dome Required for ...

Your thoughts are appreciated Thanks.

Where is $ ('expenses_txt'). Live () kept the piece? It seems that it is being triggered multiple times

Set a breakpoint (click on the firebug script tab, margin on the left margin of the line number) on $ ('expenses_txt'). Live () line should trigger it only once. If it triggers multiple times, you will easily see a stack trace (which you should take back to the culprit).

Also, set a breakpoint (where you use Typewitch) during closing. The type watch part can be offender because it is reinstating every keyboard (whether it is already "treated" (and sometimes callback bound) this .

< P> If this is the type of work, you want to see if it is tied in some way. The simplest thing is to flag the DOM element in some way. For example, you can use: 

  jQuery ('#  
  Check it using jQuery (' # element '):  
 )  
 
 To see the plugin docs, the authors are responsible for someone like this.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
