为一个类制作样式并为其他人删除它

Question

我想为一个<text>in创建一个 css 类<svg>，并为所有具有相同类的对象删除此类<text>，类似这样：  $('.svg-text').on('click', function () {      var id = $(this).attr('rel');        $(this).addClass("svg-style").siblings(".svg-text").removeClass("svg-style");    });这是一个<text>标签的例子<svg>：<g id="Group-4" transform="translate(13.000000, 336.000000)">    <text rel="text-2"  class="svg-text" id="Publication-des-résu" font-family="Roboto-Bold, Roboto" font-size="12" font-weight="bold" line-spacing="16" fill="#191919">        <tspan x="25" y="11">PUBLICATION DES RÉSULTATS DE TEST</tspan>    </text>    <g id="Group-9-Copy-6">        <circle id="Oval" stroke="#B5004F" stroke-width="1.5" cx="7.42857143" cy="7.42857143" r="7.42857143"></circle>        <g id="info" transform="translate(5.714286, 3.428571)" fill="#B5004F" fill-rule="nonzero">        </g>    </g></g><g id="Group-5" transform="translate(13.000000, 367.000000)">    <text rel="text-3"  class="svg-text" id="Vérification-de-la-c" font-family="Roboto-Bold, Roboto" font-size="12" font-weight="bold" line-spacing="16" fill="#191919">        <tspan x="25" y="11">VÉRIFICATION DE LA CONFORMITÉ</tspan>    </text>    <g id="Group-9-Copy-7">        <circle id="Oval" stroke="#B5004F" stroke-width="1.5" cx="7.42857143" cy="7.42857143" r="7.42857143"></circle>        <g id="info" transform="translate(5.714286, 3.428571)" fill="#B5004F" fill-rule="nonzero">        </g>    </g></g>

Answer 1

$('.svg-text').on('click', function() {

  //on every click

  var id = $(this).attr('rel');

  $("text.svg-text").removeClass("svg-style");

  // first remove class from every text with class .svg-text

  $(this).addClass("svg-style");

  // then re-apply on only clicked one

});

.svg-text {

  background-color: red

}

.svg-style {

  background-color: blue

}

Answer 2

如果您将此用作 onlclick 函数，您将首先从具有类 svg-text 的 s 中清除所有 svg-style （如果有），然后将 svg-style 添加到单击的文本。

  var elements = document.getElementsByClassName("svg-text svg-style");

  if (elements){

    for (i=0;i<elements.length;i++) {

      elements[i].classList.remove("svg-style");

    }

  }

  this.classList.add("svg-style");
