Iterating through a set Morris Donuts in ASP.NET application using jQuery and move text outside

问题

TL;DR: 1. Iterate through all donuts within a Div. 2. Move label text outside the donut on mouseOver.

I came across this and this questions that got me half way there, but I am trying to iterate through several donuts. I'm new to jQuery and I've tried a few options, but I just don't have a complete understanding.

Here's my code. Any help would be appreciated:

HTML

    `<div class="dials">
<div class="row">
        <div class="col-md-4">
            <asp:Label ID="lblSurvey1" Text="" runat="server" CssClass="page-subheader" />
            <div id="divSurvey1"></div><span id="morrisDonutChartSpan"></span>
        </div>
        <div class="col-md-4">
            <asp:Label ID="lblSurvey2" Text="" runat="server" CssClass="page-subheader" />
            <div id="divSurvey2"></div><span id="morrisDonutChartSpan"></span>
        </div>
    </div>
</div>`

Donut script:

Morris.Donut({
    element: 'divSurvey1',
    colors: ['#2299DE', '#97C240', '#2c594f', '#002D40', '#BC0D20', '#FF8922', '#f0b71e', '#9369d2'],
    labelColor: '#B5B5B5',
    resize: false,
    data: [
      <asp:Literal id="litSurvey1Data" runat="server"></asp:Literal>
]
});

Morris.Donut({
    element: 'divSurvey2',
    colors: ['#2299DE', '#97C240', '#2c594f', '#002D40', '#BC0D20', '#FF8922', '#f0b71e', '#9369d2'],
    labelColor: '#B5B5B5',
    resize: false,
    data: [
      <asp:Literal id="litSurvey2Data" runat="server"></asp:Literal>
]
});

    $( ".dial" ).mouseover(function() {
        prepareMorrisDonutChart();
    });

    $( document ).ready(function() {
        prepareMorrisDonutChart();
    });

    function prepareMorrisDonutChart() {
        $(".dial tspan:first").css("display","none");
        $(".dial tspan:nth-child(1)").css("font-size","40px");

        var isi = $(".dial tspan:first").html();
        $('.dial').text(isi);
    }

Maybe a bit overkill, but I got it to work. Thought I'd share the code and make someone happy out there lol.
