单击 SVG 元素时应用 CSS 样式

Question

I am trying to set the CSS style for the clicked element. I have tried to put :active :clicked :targed with the class name and none of these worked. :hover effect works fine. Thanks for the answers.

HTML:

<a (click)="Clicked(14)" class="lankstumas">
    <ellipse
    class="e-image"
       id="path3769-9"
       cx="43.089287"
       cy="103.09822"
       rx="43.845238"
       ry="39.498512"
       style="fill:#ff7f2a;stroke-width:0.26458332" />
    <text
    class="e-text"
       xml:space="preserve"
       style="font-style:normal;font-weight:normal;font-size:10.58333302px;line-height:1.25;font-family:sans-serif;letter-spacing:0px;word-spacing:0px;fill:#000000;fill-opacity:1;stroke:none;stroke-width:0.26458332"
       x="22.300594"
       y="99.318459"
       id="text3836"><tspan
         sodipodi:role="line"
         id="tspan3834"
         x="22.300594"
         y="99.318459"
         style="stroke-width:0.26458332">LANKS - </tspan><tspan
         sodipodi:role="line"
         x="22.300594"
         y="112.54762"
         style="stroke-width:0.26458332"
         id="tspan3838">TUMAS</tspan></text>
         </a>

CSS:

.lankstumas:hover{
        .e-image{
            transition: .2s fill;
            fill: #FF8504!important; 
        }
        .e.text{
            transition: .2s fill;
            fill:#fff!important;
        }
        }

I am trying to set the CSS style for the clicked element.

One approach to achieve this effect is to give the element an HTML5 Custom data-* attribute like this:

data-clicked="false"

You can then use javascript, to detect a click on the element and update the attribute.

To detect the click with javascript, use:

myElement.addEventListener('click', myFunction, false);

To modify the attribute use:

myElement.dataset.myAttribute = myValue;

Working Example:

 const boxes = document.getElementsByClassName('box'); const showClick = (e) => { event.target.dataset.clicked = 'true'; } for (let i = 0; i < boxes.length; i++) { boxes[i].addEventListener('click', showClick, false); }

 .box { display: inline-block; width: 100px; height: 100px; margin: 6px; background-color: rgb(255, 0, 0); cursor: pointer; }.box::after { content: 'Click me;': display; block: text-align; center: line-height; 100px: color, rgb(255, 255; 255): font-weight; bold. }:box[data-clicked="true"] { color, rgb(255, 0; 0): background-color, rgb(255, 255; 0). }:box[data-clicked="true"]::after { content; 'Clicked:', color, rgb(255; 0, 0); }

 <div class="box" data-clicked="false"></div> <div class="box" data-clicked="false"></div> <div class="box" data-clicked="false"></div> <div class="box" data-clicked="false"></div> <div class="box" data-clicked="false"></div>

In your code you want to overwrite inline css. In order to change the color you need to delete the inline styles for the fill . Next comes an example:

 svg{border:solid;width:90vh;}.e-image{transition: .2s fill;}.lankstumas:hover.e-image{fill: skyBlue; }.lankstumas:hover.e-text{fill:#fff;}

 <svg viewBox="-5 60 100 90"> <a class="lankstumas"> <ellipse class="e-image" id="path3769-9" cx="43.089287" cy="103.09822" rx="43.845238" ry="39.498512" fill="#ff7f2a" /> <text class="e-text" xml:space="preserve" style="font-style:normal;font-weight:normal;font-size:10.58333302px;line-height:1.25;font-family:sans-serif;letter-spacing:0px;word-spacing:0px;stroke:none;stroke-width:0.26458332" x="22.300594" y="99.318459" id="text3836"> <tspan sodipodi:role="line" id="tspan3834" x="22.300594" y="99.318459" style="stroke-width:0.26458332">LANKS - </tspan><tspan sodipodi:role="line" x="22.300594" y="112.54762" style="stroke-width:0.26458332" id="tspan3838">TUMAS</tspan></text> </a> </svg>
