HTML text hiding skills and applications

HTML text hiding is a very practical skill in network development. It is often used in some special occasions: such as showing text in different languages, but it needs to be obvious Click to mark; or embed some subscriber-specific content in the web page, which requires subscription confirmation before viewing. This article will explain in detail the implementation method of HTML text hiding and explore the practical application of this technique.

Implementation method

HTML text hiding can be achieved in three ways:

1. CSS style

This is the most Simple way to implement. We create a <span> element in HTML and then hide it via CSS styling. The specific implementation method is as follows:

<span style="display:none;">要隐藏的文本内容</span>

display:none is the command to hide the entire text content. The advantage of this method is that it is simple to implement, but the disadvantage is that it needs to be hard-coded in the style, which is not conducive to later modification and management.

2. Element attributes

This implementation method is also very simple. We can create a <span> element in HTML and hide the text by setting its attributes. Specifically, it can be implemented as follows:

<span hidden>要隐藏的文本内容</span>

This method sets the hidden attribute to true to hide the text content. The advantage of this approach is that it does not require an additional style attribute, the disadvantage is that this attribute may be ignored by the browser in some cases.

3. Javascript

This implementation requires the use of Javascript to control text hiding. We can create a <div> element or a <span> element in HTML and hide the text inside it by using Javascript script. The specific implementation method is as follows:

<div id="myDiv">要隐藏的文本内容</div>
<script>
document.getElementById("myDiv").style.display="none";
</script>

This method requires additional Javascript scripts to control the display and hiding of elements. In some cases, this method may have the same effect as the CSS style implementation method, but it is more flexible and customizable.

Application scenarios

Using HTML text hiding techniques, we can achieve very diverse application scenarios. Below we will briefly introduce some common application scenarios.

1. Multi-language text

If we need to place multiple language versions of text in the web page, we can achieve it through HTML text hiding techniques. For example, now we need to display a text that alternates between Chinese and English:

<div>
  中文
  <span style="display:none;">英文</span>
</div>

Use CSS style methods to hide the <span> tag, and when the user clicks on the text, we can use Javascript Script to control the display or hiding of <span> tags.

2. Subscriber-exclusive content

If we need to place some subscriber-exclusive content on the web page, we can use HTML text hiding and Javascript scripts to achieve it. For example, we place a piece of text on a web page, but the text can only be viewed by subscribed users. We can hide this text and prompt the user to subscribe first.

<div>
  您必须订阅本网站才能查看该内容。
  <span style="display:none;">订阅用户可查看的内容</span>
</div>
<script>
  // 判断用户是否已经订阅，如果已经订阅，则通过Javascript脚本显示隐藏的内容
  if (isSubscribed()) {
    document.querySelector('span').style.display = 'block';
  }
</script>

3. Hide sensitive text content

If we need to place some sensitive text content in the web page, under the condition that only authorized users can view it, we can use HTML Text hiding techniques and Javascript scripts to achieve. For example, we placed a piece of sensitive text on a web page, but only authorized users could view it. We can hide this text and prompt the user to log in or authorize first.

<div>
  请先登录或授权才能查看
  <span style="display:none;">授权用户可查看的敏感文本内容</span>
</div>
<script>
  // 判断用户是否已经登录或授权，如果已经登录或授权，则通过Javascript脚本显示隐藏的内容
  if (isAuthorized()) {
    document.querySelector('span').style.display = 'block';
  }
</script>

Summary

HTML text hiding techniques are widely used in web development and can be used to implement multi-language text, subscriber-specific content, hiding sensitive text content and other application scenarios. Implementation methods can use CSS styles, element attributes and Javascript scripts, each with its own advantages and disadvantages. In specific applications, we need to choose a solution that suits us and design and develop it according to the specific situation.
