根据 javascript 值创建 Bootstrap 弹出框内容

Question

我正在使用 JustGage 和 Bootstrap 并希望根据 Javascript JustGage 中的值在 Popover 中显示一些可变内容。

例如，如果仪表中的值介于 0 - 50 之间，他们将获得 "Try harder"，如果它介于 50 - 200 之间，他们将获得 "Well done"，显示在弹出窗口内容中。 -（您可以通过点击仪表 1 来查看）。

    $(window).load(function() {

      var gageValue1 = getRandomInt(0, 200)
      var gageValue2 = getRandomInt(0, 200)
      var gageValue3 = getRandomInt(0, 200)
      var colorGradientRYG = ["#991D1D", "#9D1F1F", "#A22222", "#A62424", "#AB2727", "#B02929", "#B42C2C", "#B92E2E", "#BE3131", "#C23333", "#C73636", "#CC3939", "#CE4236", "#D14B33", "#D35530", "#D65E2D", "#D8672A", "#DB7127", "#DD7A24", "#E08321", "#E28D1E", "#E5961B", "#E8A019", "#E9A619", "#EBAD1A", "#ECB41A", "#EEBB1B", "#F0C21C", "#F1C81C", "#F3CF1D", "#F5D61E", "#F6DD1E", "#F8E41F", "#FAEB20", "#F4EB25", "#EEEB2B", "#E9EC31", "#E3EC36", "#DEEC3C", "#D8ED42", "#D3ED48", "#CDED4D", "#C8EE53", "#C2EE59", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BDEF5F", "#BBED5C", "#B9EC59", "#B8EA56", "#B6E954", "#B4E851", "#B3E64E", "#B1E54B", "#AFE449", "#AEE246", "#ACE143", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#ABE041", "#AAE03E", "#A9E03C", "#A8E03A", "#A8E037", "#A7E035", "#A6E033", "#A5E031", "#A5E02E", "#A4E02C", "#A3E02A", "#A3E028", "#A4E224", "#A5E520", "#A6E81D", "#A7EB19", "#A8EE15", "#A9F012", "#AAF30E", "#ABF60A", "#ACF907", "#ADFC03", "#AEFF00"]
      var g1 = new JustGage({
        id: "g1",
        title: "Gage 1",
        value: 92,
        min: 0,
        max: 200,
        showMinMax: false,
        levelColors: colorGradientRYG,
        levelColorsGradient: false,
      });
      var g2 = new JustGage({
        id: "g2",
        title: "Gage 2",
        value: 98,
        min: 0,
        max: 200,
        showMinMax: false,
        levelColors: colorGradientRYG,
        levelColorsGradient: false,
      });
      var g3 = new JustGage({
        id: "g3",
        title: "Gage 3",
        value: 77,
        min: 0,
        max: 200,
        showMinMax: false,
        levelColors: colorGradientRYG,
        levelColorsGradient: false,
      });

      $(document).ready(function() {
        $('#g1_refresh').bind('click', function() {
          g1.refresh(getRandomInt(0, 200));
          g2.refresh(getRandomInt(0, 200));
          g3.refresh(getRandomInt(0, 200));
          return false;
        });
      });
    });


    $(document).ready(function() {
      $('[data-toggle="popover"]').popover();
    });

<h3>How am i doing?</h3>

<div class="row-fluid">
  <div class="span4">
    <a class="tipsPopover" title="Tips" data-toggle="popover" data-placement="bottom" text-align="center" data-content="This will be some content including a helpful tip on how to improve, based on the value given.">
      <div id="g1">
      </div>
    </a>

  </div>
  <div class="span4">
    <div id="g2"></div>
  </div>
  <div class="span4">
    <div id="g3"></div>
  </div>
</div>

这是我目前所拥有的... https://jsfiddle.net/e4v62nh6/1/

似乎总是可以在xPath中找到初始化的JustGauge的值
//*[@id="someid"]/svg/text[2]/tspan - 这样你就可以在一个循环中创建所有的弹出窗口：

$("svg").each(function() {
    var value = +this.querySelector('text:nth-of-type(2)')
                     .querySelector('tspan')
                     .textContent;             

    function getContent() {
        if (value<20) return "Dont quit your dayjob"
        if (value<40) return "Try harder"
        if (value<60) return "Room for improvement"
        if (value<80) return "You passed the test"
        return "Well done"
    }    

    $(this).popover({
      trigger : 'hover',  
      placement : 'top', 
      content : getContent()
    });    
});
