Question

我有几个有两个类名的div，例如......

<div class="mainContainer">
    <div class="container">
        <div class="test word1.20">
    </div>
    <div class="container">
       <div class="test word3.40">
    </div>
</div>

如果第二类名称中存在小数，我想在结尾处删除小数和零，因此结果将类似于word12。请注意，我有几个像这样的div

我在想......

if .test has a decimal, do this {
    $(".container .test").each(function() {
       value1 = $(this).attr("class").replace(".", "");
       value2 = $(this).attr("class").replace("0", "");
       $(this).attr("class", value1);
       $(this).attr("class", value2);
    });
}

感谢您的见解！

您可以操作.container的HTML，如下所示：

$(function(){
  processReplacement();
  showResult();
});

processReplacement = function(){
  $("div.test").each(function(){
    var classes = $(this).prop('class');
    var regex   = /(\bword)(.*)\b/;
    
    var decimalClassName = regex.exec(classes)[2];
    var decimalClassNameFixed = parseFloat(decimalClassName).toString().replace('.', '');
    
    $(this).prop('class', classes.replace(regex, "$1" + decimalClassNameFixed));
  });
};

showResult = function(){
  $('.test').each(function(){
    $(this).text($(this).prop('class'));
  });
};

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="mainContainer">
    <div class="container">
        <div class="test word1.20"></div>
    </div>
    <div class="container">
       <div class="test word3.40"></div>
    </div>
</div>

如果类名具有特殊字符，请执行此操作
