Most of our use of CSS will use a Link tag in the web page to introduce a CSS file. Or define the CSS style in the Head tag of the web page. In fact, Dom provides several instructions. You can dynamically set or get the CSS appearance style of an element. You may have seen the "skin changing" function on other websites. This technology uses the Dom instruction to introduce a new CSS file to the current web page. Let the appearance of the web page suddenly change. Of course, you can also set the appearance of only a certain element in the current web page. Proper use can greatly improve user experience! Below I will list the Css instructions in Dom. Due to space limitations, I do not provide usage methods and example demonstrations of each Dom command on this page. You can click on the relevant Dom command name. To learn more about the detailed instructions and example demonstrations of related instructions.
Use Dom's className to specify a CSS style class name for the current element. To change the appearance style of the current element
Set multiple Css attribute styles for the current element in HTML Dom: cssText
HTML Dom The command to obtain the Css attribute value specified by the current element is: currentStyle supports IE
HTML Dom acquisition The command for the Css attribute value specified by the current element is: getPropertyValue supports FF
HTML Dom also provides a createStyleSheet command. A new CSS file can be introduced into a dynamic web page. This is the "skin-changing" function I mentioned earlier. Unfortunately, this command does not support FF and Chrome browsers, but I have solved the same effect under FF in the explanation of createStyleSheet.
Under the leadership of ajax technology. Dom has developed rapidly in recent years. It has also been taken seriously by many people. Many large websites strive to pursue a good user experience. These technologies are no longer unfamiliar! In fact, these all belong to the scope of front-end design. Nowadays, big companies such as "Baidu", "Taobao", "Tencent", etc. attach great importance to front-end design. Therefore, learning the front-end well is also a good choice. I hope what I will talk about today can help you!

1.原生js获取DOM节点:document.querySelector(选择器)document.getElementById(id选择器)document.getElementsByClassName(class选择器)....2.vue2中获取当前组件的实例对象:因为每个vue的组件实例上,都包含一个$refs对象,里面存储着对应的DOM元素或组件的引用。所以在默认情况下,组件的$refs指向一个空对象。可以先在组件上加上ref="名字",然后通过this.$refs.

vue3ref绑定dom或者组件失败原因分析场景描述在vue3中经常用到使用ref绑定组件或者dom元素的情况,很多时候,明明使用ref绑定了相关组件,但是经常ref绑定失败的情况。ref绑定失败情况举例ref绑定失败的绝大多数情况是,在ref和组件绑定的时候,该组件还未渲染,所以绑定失败。或者组件刚开始未渲染,ref未绑定,当组件开始渲染,ref也开始绑定,但是ref和组件并未绑定完成,这个时候使用组件相关的方法就会出现问题。ref绑定的组件使用了v-if,或者他的父组件使用了v-if导致页面

bom和dom在作用和功能、与JavaScript的关系、相互依赖性、不同浏览器的兼容性和安全性考虑等方面都有区别。详细介绍:1、作用和功能,BOM的主要作用是操作浏览器窗口,它提供了浏览器窗口的直接访问和控制,而DOM的主要作用则是将网页文档转换为一个对象树,允许开发者通过这个对象树来获取和修改网页的元素和内容;2、与JavaScript的关系等等。
