1. children in Jquery
Grammar
.children(selector)
Description
expr is an expression, optional parameter. All expressions in the selector can be used here, such as by tag name "div", by class name ".class", by sequence number ":first", etc. If the expression is empty, all children are returned and the returned result is still a jQuery object.
2. Find
in Jquery
The find() method obtains the descendants of each element in the current element collection, filtered by selectors, jQuery objects, or elements.
Grammar
.find(selector)
Description
It accepts a selector expression of the same type as the expression we passed to the $() function. Elements will be filtered by testing whether they match the expression.
3. The difference between children and find in jquery
1. The children and find methods are both used to obtain the child elements of element. Neither of them will return text node, just like most jQuery methods.
2. The children method only obtains the child elements below the element
3. The find method obtains all subordinate elements
4. The parameter selector of the children method is optional (optionally) and is used to filter child elements, but the parameter selector of the find method is required.
5. The find method can actually be implemented by using jQuery (selector, context)
