javascript - Using jQuery, a Dropdownlist should only be visible if at least 1 checkbox is selected -


I have the link, when clicked, select or deselect all checkboxes.

I also have the dropdown list which I would like to show if at least one checkbox is selected.

What is the best way to do this?

Should I enter the code inside the code that he chooses / deletes it or is there a better way of doing this?

I will have a function that sets the visibility of the dropdown I will assign this function to each checkbox and link handler I would say click handlers - I assume that your link handlers do not fire only one click event on each box, but set its position. Unless you have any other behavior to trigger click event firing on each checkbox, it will be very expensive, use the test of the set in your function, use a test, to see if the number of check boxes visibility Is more than 0 for. 

  function setDDVisibility () {var isvisible = $ ('.checkbox-class-selector: checked'). Length & gt; 0; If (invisible) {$ ('# ddl'). Show (); } And {$ ('# ddl'). Hide (); }} $ ('Checkbox-square'). Click (function () {... do stuff ... setDDVisibility (); return false;}); $ ('Link-selector'). Click (function () {... set up checkbox ... set DD viability (); return returned;});

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...
