Question

我想创建货币代码。查询从yahoo Finance API检索值并将其显示为文本。主要问题是文本末尾的空格。字幕脚本marquee plugin解决差距问题。 setInterval会中断移动文本，因为它从头开始。

＆＃13;

     $(document).ready(function() {
       //StockPriceTicker();
       setInterval(StockPriceTicker, 5000);
     });

     function StockPriceTicker() {
       var Symbol = "",
         CompName = "",
         Price = "",
         ChnageInPrice = "",
         PercentChnageInPrice = "";
       var CNames = "^FTSE,HSBA.L,SL.L,BATS.L,BLND.L,FLG.L,RBS.L,RMG.L,VOD.L";
       var flickerAPI = "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22" + CNames + "%22)&env=store://datatables.org/alltableswithkeys";
       var StockTickerHTML = "";

       var StockTickerXML = $.get(flickerAPI, function(xml) {
         $(xml).find("quote").each(function() {
           Symbol = $(this).attr("symbol");
           $(this).find("Name").each(function() {
             CompName = $(this).text();
           });
           $(this).find("LastTradePriceOnly").each(function() {
             Price = $(this).text();
           });
           $(this).find("Change").each(function() {
             ChnageInPrice = $(this).text();
           });
           $(this).find("PercentChange").each(function() {
             PercentChnageInPrice = $(this).text();
           });

           StockTickerHTML += "<span>" + CompName + " " + Price + "</span>";
         });

         $(".marquee div").html(StockTickerHTML);
         //$("#dvStockTicker").jStockTicker({interval: 30, speed: 2});
       });
     }

＆＃13;

body {
  margin: 20px;
}
.marquee {
  height: 25px;
  width: 420px;
  overflow: hidden;
  position: relative;
}
.marquee div {
  display: block;
  width: 200%;
  height: 30px;
  position: absolute;
  overflow: hidden;
  animation: marquee 5s linear infinite;
}
.marquee span {
  float: left;
  width: 50%;
}
@keyframes marquee {
  0% {
    left: 0;
  }
  100% {
    left: -100%;
  }
}

<div class="marquee">

Answer 1

问题是你给了span一个固定的宽度，如果文字较小，那么每个文本的末尾会有一个很大的空白空格，所以通过这样调整.marquee span规则解决这个问题

.marquee span {
    display: inline-block;
}
.marquee span ~ span::before {
    content:'|';
    color: red;
    padding: 0 5px
}

文字中断是由.marquee div上的固定宽度引起的，所以我也对那个进行了一些调整

.marquee div {
    display: inline-block;
    padding-left: 100%;          /*  start from right, can be removed  */
    animation: marquee 25s linear 2s infinite;
}
