javascript - Updating a select box without causing onChange -


What do I want to achieve here, I have a selection box that loads in some rows, when the selection changes The (onchange) key is used in the PHP function as AJAX, which gives an array in JSON format, then my code selection box clears options and applies the values ​​that I have just returned from my PHP function .

The problem when the new values ​​are set, it fires the on-event event again, it sets the value and we are in the beginning of a non-ending loop, there is an error in firebug Goes out and goes out of it.

My question is that there is a way to disable the incident of attack, so it only takes a fire. I am coding in a structure around the prototype, posting a code example would be a bit heavy, although I can try to fill any missing data on the request.

Cheers! ILMV

Using flag variable, worry about stopping onchange Instead, wrap your logic in a conditionally condition based on a flag variable. Basically you can only create a variable , and set it to false when you are updating the program, then, onchange logic Check the value of that variable if it is wrong, do not do anything, but toggle it to the next onchange event true if it is true, then its Make specific AJAX requests for data.

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...
