I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's learn about it.

In jquery, ">" is a child element selector that can only select child elements of an element; the syntax "$(" E > F ")", where E is the parent element and F is the child element, indicates that all child elements F under the E element are selected.

The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.

In jquery, ">" refers to a child element selector, which is a kind of hierarchical selector.

The child element selector (E > F) can only select the child elements of an element, where E is the parent element and F is the child element, where E > F indicates that all child elements F under the E element are selected.

Syntax:

$("E > F")

All selectors in jQuery begin with the dollar sign: $().

Return value: returns the matching result set

Example:

$(document) .ready (function () {$("# main > *") .css ("border", "3px double red");}); body {font-size: 14px } span#main {display: block; background: yellow; height: 110px } button {display: block; float: left; margin: 2px; font-size: 14px } div {width: 90px; height: 90px; margin: 5px; float: left; background: # bbf Font-weight: bold;} div.mini {width: 30px; height: 30px; background: green } Child Grand A Span in child A Span in main

Analysis:

("# main > *") .css ("border", "3px double red")
