我的代码 - Fiddle

$(function() {
  var makeSlider = function(params) {
    var defaults = {
      id: 1,
      amountPurchases: 0,
      pricePlus: 0,
      offset: 140,
      onStart: function(data) {
        //console.log("onStart");
        irsSingleNew();
      }
    };

    var options = $.extend({}, defaults, params);

    var rangeContainer = $('.range-slider-container-' + options.id);
    var rangeDiscount = $('.range-discount-' + options.id);
    
    // I'm trying to replace content .irs-single
    // But replacing the text in my text does not happen
    function irsSingleNew() {
      var irsSingle = rangeContainer.find('.irs-single');
      var irsSingleAmountPurchases = irsSingle.html('<span class="irs-single">' +options.amountPurchases+ ' $' + '</span>');
      console.log(options.amountPurchases);
    }

    rangeDiscount.ionRangeSlider({
      type: "single",
      grid_snap: true,
      postfix: " $",
      onStart: options.onStart
    });

    rangeContainer.find('.irs').on('change click', '.irs', function() {

      $(this).append('<span class="irs-price-plus">+' + options.pricePlus + ' $</span>');

      var irsSingle = rangeContainer.find('.irs-single'),
        irsSingleOffset = irsSingle.position(),
        irsSingleOffsetLeft = irsSingleOffset.left;
      //console.log(irsSingleOffsetLeft);

      var irsPricePlus = rangeContainer.find('.irs-price-plus');

      irsPricePlus.css({
        left: irsSingleOffsetLeft + options.offset + 'px'
      });
    }).trigger('click');
  }

我正在尝试替换内容.irs-single

var irsSingle = rangeContainer.find('.irs-single');
var irsSingleAmountPurchases = irsSingle.html('<span class="irs-single">' +options.amountPurchases+ ' $' + '</span>');

但是替换我的文本中的文本并没有发生

为什么这个方法不行？

如何正确替换此块的文字？

谢谢

我很乐意提供任何帮助

Answer 1

这是一个小例子

for (var i = 1; i < 6; i++) {
    var text = 'test'+i; 
    var t = $('<li />', {html: text}).appendTo('ul.justList');
    $(t).text('hello')    
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="justList"></ul>
