Implement jQuery to close multiple div elements

My dilemma involves a series of divs with different manufacturer IDs listed as follows:

manufacturer[1], manufacturer[2], manufacturer[3], ... etc ...

In attempting to create a JavaScript for loop to hide each div, I discovered that it was not achievable.

I realized that in this context, closing the divs actually meant hiding them (display:none).

So, now I require assistance in composing a simple jQuery code snippet to accomplish this task:

    function hideAllManufacturers(manufacturersID)
{
    var manufacturer = [1,2,3,];

    $.each(manufacturer, function(index, val) {
        $('.manufacturer['+val+']').hide();
    });
}

Although my code implementation works, the subsequent code is not being displayed. This leads me to believe there may be an issue with what I have written.

I am curious if having a comma at the end is causing any problems?

Your guidance is much appreciated!

Answer №1

If you want to use a wildcard, here's how you can do it:

$('[class^="manufacturer"]').hide();

This code will hide any element that has a class starting with "manufacturer". For example, it will hide .manufacturer[1], .manufacturer[2], and so on.

Using this method will make your code more efficient in the long run. You won't have to constantly update the manufacturer array in jQuery every time you add a new manufacturer. The wildcard will automatically include any new additions, saving you time and unnecessary code.

Answer №2

The reason for this issue is that the square brackets [] are considered meta characters in CSS selectors used by JQuery, so they need to be escaped with two backslashes \\ as shown below:

$(".manufacturer\\[" + val + "\\]").hide();

For more information, please refer to:

http://api.jquery.com/category/selectors/

http://www.w3.org/TR/CSS21/syndata.html#value-def-identifier

Another issue causing it not to work is the extra comma at the end of your array:

var manufacturer = [1,2,3,]; //please remove the last comma

It should be corrected like this:

var manufacturer = [1,2,3];
