如何在输入中添加SVG图标? [英] How to add a SVG icon within an input?

问题描述

我需要在输入中放置图标以创建新用户.对于熟悉前端代码的人来说，这可能是一项非常简单的任务.但是我没有.这是线框，然后显示代码.

I need to place icons within the inputs for creating a new user. It's probably a really easy task for someone who knows their way around front end code. However I don't. Here is the wireframe and then I show my code.

如您所见.输入的左侧有图标.现在，我在目录中有SVG，可以开始使用了，我只需要知道如何将它们放在输入中即可.这是表格的代码

As you can see. There are icons on the left side of the inputs. Right now I have the SVG's in my directory and ready to go I just need to know how to place them within the input. Here is the code for the form

<label clas="name-label">
  <%= f.text_field :name, placeholder: "Name", class: "form-labels" %>
</label>

<label class="email-label">
  <%= f.text_field :email, placeholder: "Email", class: "form-labels" %>
</label> 

所以我有一个带字符串的占位符，当前仅打印该字符串.我需要将图标放在我认为的范围内吗?这是我要用于图标的CSS.

So I have the placeholder with a string which currently just printing that string. I need to put the icons within that I think? Here is the css I have for the icons.

.icon-email {
  background-image: image-url('email-field.svg');
}

.icon-name {
 background-image: image-url('name-field.svg');
}

有没有办法将这些类放置在占位符中?

Is there a way I can place these classes within the place holder?

推荐答案

您可以在<label>标记中添加一个伪元素，并使用一些position和padding技巧进行视觉效果.使用svg作为背景与使用图片相同.

You can add a pseudo element in the <label> tag, and use some position and padding tricks for the visual. Using a svg for background is just the same as using an image.

label {
  position: relative;
}

label:before {
  content: "";
  position: absolute;
  left: 10px;
  top: 0;
  bottom: 0;
  width: 20px;
  background: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='25' height='25' viewBox='0 0 25 25' fill-rule='evenodd'%3E%3Cpath d='M16.036 18.455l2.404-2.405 5.586 5.587-2.404 2.404zM8.5 2C12.1 2 15 4.9 15 8.5S12.1 15 8.5 15 2 12.1 2 8.5 4.9 2 8.5 2zm0-2C3.8 0 0 3.8 0 8.5S3.8 17 8.5 17 17 13.2 17 8.5 13.2 0 8.5 0zM15 16a1 1 0 1 1 2 0 1 1 0 1 1-2 0'%3E%3C/path%3E%3C/svg%3E") center / contain no-repeat;
}

input {
  padding: 10px 30px;
}

<label>
  <input type="text" placeholder="Search">
</label>
