Question

I want to make a generic function in jquery for select all functionality. I have a tabbed view in my web page.

Id of my component is : tabId:someDynamicId:rowId:componentId
where, someDynamicId is dynamically generated.

So in jquery i want to find the element whose id starts with – tabId:someDynamicId & ends with componentId. And, tabId, someDynamicId & componentId would be passed as an argument to the generic function where this element needs to be find.

Answer 1

It’s simple:

$('[id^=tabId][id$=componentId]').each(function(){
    var id = $(this).attr('id'); // tabId:someDynamicId:rowId:componentId​
    var list = id.split(':');​​

    console.log(list[0]); // tabId
    console.log(list[1]); // someDynamicId
    console.log(list[2]); // rowId
    console.log(list[3]); // componentId​
})

Wildcards in jQuery selectors

But i’m recommending to use right tools for this job. ID’s are useful for finding specific element, but in your case it’s better to use one or two classes and data attributes. For example:

<div class="tabs" data-component-id="x" data-tab-id="y">

Then find all $(‘.tabs’) elements and use $(this).data(‘component-id’) and $(this).data(‘tab-id’)

$('.tabs').each(function(){
    var component_id = $(this).data('component-id');
    var tab_id = $(this).data('tab-id');
});

Update:

There is example of using this as function:

function(tabId,componentId) {
    $('[id^='+tabId+'][id$='+componentId+']').each(function(){
        var id = $(this).attr('id'); // tabId:someDynamicId:rowId:componentId​
        var list = id.split(':');​​

        console.log(list[0]); // tabId
        console.log(list[1]); // someDynamicId
        console.log(list[2]); // rowId
        console.log(list[3]); // componentId​
    })  
}
