如何在 Hover 上更改 svg 顏色

Question

每一個，我都在使用 angular 並且我有一個 svg、html，例如：

  <button
    type="button"
    class="filter-icon-wrapper padding-0 border-0 outline-0 bg-transparent pointer"
  >
    <mat-icon class="filter-icon" *ngIf="!isDateType" svgIcon="filter_default">filter_alt</mat-icon>
  </button>

這是 svg 源代碼 filter_default：

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 11.9 11.91"><defs><style>.cls-2{fill:#707070;}</style></defs><g id="Layer_2" data-name="Layer 2"><g id="Layer_1-2" data-name="Layer 1"><g id="Path_7587" data-name="Path 7587"><path class="cls-2" d="M6.8,11.91a1,1,0,0,1-.58-.19l-1.7-1.19a1,1,0,0,1-.43-.83V5.52L.3,1.73A1,1,0,0,1,0,1,1,1,0,0,1,.29.3,1,1,0,0,1,1,0h9.88a1,1,0,0,1,.72.29,1,1,0,0,1,0,1.44L7.82,5.52v5.37a1,1,0,0,1-.19.59A1,1,0,0,1,6.8,11.91ZM1,1,5.09,5.11V9.7L6.8,10.9l0-5.79L10.9,1V1Z"/></g></g></g></svg>

Answer 1

 #Path_7587.cls-2 { fill:#707070; } #Path_7587.cls-2:hover { fill: red; }

 <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 11.9 11.91"><g id="Layer_2" data-name="Layer 2"><g id="Layer_1-2" data-name="Layer 1"><g id="Path_7587" data-name="Path 7587"><path class="cls-2" d="M6.8,11.91a1,1,0,0,1-.58-.19l-1.7-1.19a1,1,0,0,1-.43-.83V5.52L.3,1.73A1,1,0,0,1,0,1,1,1,0,0,1,.29.3,1,1,0,0,1,1,0h9.88a1,1,0,0,1,.72.29,1,1,0,0,1,0,1.44L7.82,5.52v5.37a1,1,0,0,1-.19.59A1,1,0,0,1,6.8,11.91ZM1,1,5.09,5.11V9.7L6.8,10.9l0-5.79L10.9,1V1Z"/></g></g></g></svg>

Answer 2

類似於第一個答案，有一個更正。 正確的 class 修改為cls-2 ：

.cls-2:hover {
  fill:red;
}

Answer 3

感謝您的所有幫助，我嘗試了 ng-deep，現在工作正常

1. 將 svg 中的 class 名稱從 cls-2 重命名為 floatTextIcon

2. 在 scss 文件中添加這樣的代碼

   :host::ng-deep.floatTextIcon:hover { 填充：#3a464d; }

Answer 4

懸停按鈕時更改圖標顏色：

button .cls-2 {
  fill: #888;
}

button:hover .cls-2 {
  fill: blue;
}

 button { width: 50px; height: 50px; } button.cls-2 { fill: #888; } button:hover.cls-2 { fill: blue; }

 <button> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 11.9 11.91"><g id="Layer_2" data-name="Layer 2" width="32" height="32"><g id="Layer_1-2" data-name="Layer 1"><g id="Path_7587" data-name="Path 7587"><path class="cls-2" d="M6.8,11.91a1,1,0,0,1-.58-.19l-1.7-1.19a1,1,0,0,1-.43-.83V5.52L.3,1.73A1,1,0,0,1,0,1,1,1,0,0,1,.29.3,1,1,0,0,1,1,0h9.88a1,1,0,0,1,.72.29,1,1,0,0,1,0,1.44L7.82,5.52v5.37a1,1,0,0,1-.19.59A1,1,0,0,1,6.8,11.91ZM1,1,5.09,5.11V9.7L6.8,10.9l0-5.79L10.9,1V1Z"/></g></g></g></svg> </button>
