This paper thoroughly examines why the CSS attribute selector input[type='text'] fails to match text input elements without explicitly declared type attributes. By analyzing the interaction mechanism between DOM trees and rendering engines, it reveals that attribute selectors only match based on explicitly defined attributes in the DOM. The article provides two practical solutions: using the combined selector input:not([type]), input[type='text'] to cover all text inputs, or explicitly declaring type attributes in HTML. Through comparing the differences between element and element[attr] selectors, it explains the design necessity of maintaining attribute selector strictness.

This article delves into how to dynamically create HTML table header elements (<th>) and attach click event handlers in JavaScript. By analyzing a user query scenario—where a user wants to delete a column by clicking on a dynamically generated header—we detail the complete process of using the document.createElement() method to create elements, setting innerHTML content, and binding event functions via the onclick property. The focus is on explaining the this keyword's reference in event handlers and how to dynamically remove DOM elements using parentElement and removeChild(). Additionally, alternative approaches, such as hiding elements by setting the display property instead of deleting them, are briefly discussed. This article aims to provide front-end developers with practical DOM manipulation techniques and deepen their understanding of event handling mechanisms.
