Question

So I see here how to add a div and here how to add a class but I’m having trouble combining the two. I want to generate a whole bunch of div’s with a specific class and id within the div sparkLineContainer.

I have the containing div

<div id="#sparkLineContainer"></div>

and I want to add a bunch of the following to it

    <div id="#sparkLineContainer">
        <div class="sparkLines" id="id1">Some stuff here</div>
        <div class="sparkLines" id="id2">Some stuff here</div>
        <div class="sparkLines" id="id3">Some stuff here</div>
// and so on
    </div>

snippet – I didn’t make it very far, I’m stumped

$('#sparkContainer').add("div");  \\ How do I add the id and class to this div?
                                  \\ And as a repeat the function will it overwrite this?

The function I’m trying to do this with.

function renderSparklines (array1, sparkLineName, id) {
// array1 is the data for the spark line
// sparkLineName is the name of the data.  
// Turn all array values into integers
arrayStringToInt(array1);

    // Create new div of class sparkLines
$('#sparkContainer').add("div")

    // Render new spark line to
$('.sparkLines').sparkline(array1, {width:'90px'});

var htmlString = "";  //  Content to be added to new div
//  GENERATE LITTLE SPARK BOX 
    htmlString += 
                '<font class = "blueDescriptor">' + sparkLineName + '</font>'+
                '<br>'+
                '<font class = "greyDescriptorSmall">Ship to Shore</font>'+
                '<br>'+
                '<font class = "blackDescriptorSparkLine">' + array1[array1.length-1] + '</font>'+
                '<font class = "greenDescriptorSparkline">(' + (array1[array1.length-1] - array1[array1.length-2]) + ')</font>' +
                '<br>';
    $('.sparkLines').prepend(htmlString);

}

Answer 1

You need .append or .prepend to add a div to the container. See my version below,

var $sparkLines = $('.sparkLines');
$("#sparkLineContainer")
   .append('<div id="id' + 
            ($sparkLines.length + 1) + 
            '" class="sparkLines">Some Stuff Here</div>')

Also I noticed that you have id of the div as #sparkLineContainer. You should change it as below,

<div id="sparkLineContainer"> 
...
