jquery - 条形图插件 - 使每个条形图都可点击(每个条形图都有不同的链接)

Question

我用过一个插件 http://www.jqueryscript.net/demo/Simple-Bar-Chart-Plugin-with-jQuery-Bootstrap-jchart/但问题是，我无法使条形图可点击。我的 moto 是制作每个栏链接，如果用户单击它，它将在新链接上重定向用户。但我做不到，我试过但只能为每个栏提供一个 url。请帮我html页面上的代码:

<div id="bar_of_pies" data-sort="true" data-width="300" class="jChart chart-sm" name="">

                    <div class="define-chart-row "  data-color="#dfdfdf"  title="1">13</div>
                    <div class="define-chart-row"  data-color="#F4BE44" title="2">22</div>
                    <div class="define-chart-row"  data-color="#dfdfdf" title="3">20</div>
                    <div class="define-chart-row"  data-color="#F4BE44" title="4">18</div>
                    <div class="define-chart-row"  data-color="#dfdfdf" title="5">16</div>
                    <div class="define-chart-row"  data-color="#F4BE44" title="6">14</div>
                    <div class="define-chart-row"  data-color="#dfdfdf" title="5">12</div>
                    <div class="define-chart-row"  data-color="#F4BE44" title="6">10</div>
                    <div class="define-chart-footer">10</div>
                    <div class="define-chart-footer">20</div>
                    <div class="define-chart-footer">30</div>

                </div>

js 到事件图:

$(document).ready(function () {

                        $("#bar_of_pies").jChart({
                        sort: false,
                        x_label:'Hello',

                        });
                    })
                    });

我已经 fork 了你的 fiddle 并在这里更新了它: http://jsfiddle.net/5ryEZ/5/

变化:必须编辑该插件才能使其工作。我将整个插件复制到 document.ready() 并进行了更改。

<div class="define-chart-row" data-clicker="http://google.com" data-color="#009182" title="1">13</div>

您的 document.ready 代码位于底部。对于 url，将“data-clicker”属性添加到 div。

/* replace this code in the jChart.js */
    $.fn.jChart = function (options) {
        var selector = $(this);
        var default_color = "#6b9bd6";
        var bar_height = 19;

        var settings = $.extend({
            width: 750,
            clicker: "http://wditot.in",
            name: null,
            type: "bar",
            headers: null,
            values: null,
            footers: Array(),
            sort: false,
            sort_colors: false,
            colors: Array(),
            x_label: null
        }, options);

        //Initialize some settings that can be set via HTML
        if (settings.name == null) {
            settings.name = $(this).attr("name");
        }
        if ($(this).data("sort") == true) {
            settings.sort = true;
        }
        if ($(this).data("width") != null) {
            settings.width = parseInt($(this).data("width"));
        }
        if ($(this).data("x_label") != null) {
            settings.x_label = $(this).data("x_label");
        }
        if ($(this).data("clicker") != null) {
            settings.clicker = $(this).data("clicker");
        }
        var chart_width = settings.width;
        if ($(this).hasClass("chart-sm")) {
            bar_height = 17;
        } else if ($(this).hasClass("chart-lg")) {
            bar_height = 25;
        } else if (settings.width != null) {
            chart_width = parseInt(settings.width);
        }

        checkForHTMLSettings();

        //Clear the data in the jChart div
        $(this).html("");

        //Create the html containers for the chart
