javascript delete table row

May 21, 2023 am 10:01 AM

In JavaScript, we can easily delete a row in a table through DOM manipulation. The following will introduce two basic ways to delete a row in the table.

  1. Deletion is achieved through the deleteRow() method of the table table object

In HTML, you can assign an id to the row number to be deleted or specify the row number to be deleted. row position to achieve deletion. The code is as follows:

Code description:

  • The deleteRow() method in this method is used to delete the row at the specified position (counted from 0).
  • In this example, the first row is at position 0, the second row at position 1, and so on.
  • If the row to be deleted is not in the table, an error will be thrown.
  • You need to introduce a variable corresponding to the table. The value of the variable can be obtained by using getElementById() or other methods.
  1. Deletion through the parentNode attribute of the HTMLElement object

In addition to the above method, we can also use the parentNode attribute to delete elements. In HTML, we can delete a row by getting the parent element of the currently selected row element, that is, the tbody element of the table. The code is as follows:

Code description:

  • First get the row element to be deleted, you can use the getElementById() method or other methods to get it.
  • Then use the parentNode property of the row element object to get the table table object, and get the tbody element from the object.
  • Finally, use the removeChild() method of the tbody object to remove the selected row elements.

Summary

Deleting a row in a table is easy, either using the deleteRow() method or using the parentNode attribute. Many developers prefer using the deleteRow() method, given its advantages of simplicity and clarity. On the other hand, using the parentNode attribute is a more general approach that can be used on any element in an HTML document. For developers who want to implement reusable functionality, using the parentNode attribute is undoubtedly more suitable.

Updating State Correctly with useState() in ReactUpdating State Correctly with useState() in ReactApr 29, 2025 am 12:42 AM

Correct update of useState() state in React requires understanding the details of state management. 1) Use functional updates to handle asynchronous updates. 2) Create a new state object or array to avoid directly modifying the state. 3) Use a single state object to manage complex forms. 4) Use anti-shake technology to optimize performance. These methods can help developers avoid common problems and write more robust React applications.

React's componentized architecture makes scalable UI development efficient through modularity, reusability and maintainability. 1) Modularity allows the UI to be broken down into components that can be independently developed and tested; 2) Component reusability saves time and maintains consistency in different projects; 3) Maintainability makes problem positioning and updating easier, but components need to be avoided overcomplexity and deep nesting.
