# JQuerySelector `JQuerySelector` class is used for finding DOM elements using jQuery selector mechanism. jQuery uses Sizzle as its search engine (which you can use directly by using `SizzleSelector`), however it also contains additional features like traversing methods that Sizzle itself does not support. ## Constuctor Initializes a new instance of the `JQuerySelector` class. {% tabs %} {% tab title="C#" %} The basic constructor with the selector string as an argument. ```csharp var selector = new JQuerySelector(":text"); ``` {% endtab %} {% tab title="C#" %} The constructor with the nested `JQuerySelector` context will invoke the nested context selector first, and on the results of this selector will perform the new query further narrowing the results. ```csharp var selector = new JQuerySelector(":text", By.JQuerySelector("div.myClass")); ``` {% endtab %} {% tab title="C#" %} The constructor with the alternative jQuery variable name specified. This can be useful in cases where the variable name conflicts with other libraries. ```csharp var selector = new JQuerySelector(":text", variable: "myJQuery")); ``` {% endtab %} {% endtabs %} ## Add {% tabs %} {% tab title="C#" %} Adds elements to the set of matched elements. ```csharp var selector = new JQuerySelector("div").Add("p"); ``` {% endtab %} {% tab title="C#" %} Adds elements to the set of matched elements. ```csharp var selector = new JQuerySelector("div").Add("p", new JQuerySelector("footer")); ``` {% endtab %} {% endtabs %} ## AddBack Add the previous set of elements on the stack to the current set, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Find("span").AddBack(); ``` ## AndSelf Add the previous set of elements on the stack to the current set. ```csharp var selector = new JQuerySelector("div").Find("span").AndSelf(); ``` ## Children Get the children of each element in the set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Children("span"); ``` ## Closest For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree. ```csharp var selector = new JQuerySelector("div").Closest("article"); ``` ## Contents Get the children of each element in the set of matched elements, including text and comment nodes. ```csharp var selector = new JQuerySelector("div").Contents(); ``` ## End End the most recent filtering operation in the current chain and return the set of matched elements to its previous state. ```csharp var selector = new JQuerySelector("div").Filter(".class").End(); ``` ## Eq Reduce the set of matched elements to the one at the specified index. ```csharp var selector = new JQuerySelector("div").Eq(3); ``` ## Filter Reduce the set of matched elements to those that match the selector or pass the function's test. ```csharp var selector = new JQuerySelector("div").Filter(".class"); ``` ## Find Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element. ```csharp var selector = new JQuerySelector("div").Find(".class"); ``` ## First Reduce the set of matched elements to the first in the set. ```csharp var selector = new JQuerySelector("div").First(); ``` ## Has Reduce the set of matched elements to those that have a descendant that matches the selector or DOM element. ```csharp var selector = new JQuerySelector("div").Has("span"); ``` ## Is Check the current matched set of elements against a selector, element, or jQuery object and return true if at least one of these elements matches the given arguments. ```csharp var selector = new JQuerySelector("div").Is(".class"); ``` ## Last Reduce the set of matched elements to the final one in the set. ```csharp var selector = new JQuerySelector("div").Last(); ``` ## Next Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector. ```csharp var selector = new JQuerySelector("div").Next("div"); ``` ## NextAll Get all following siblings of each element in the set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").NextAll("div"); ``` ## NextUntil Get all following siblings of each element up to but not including the element matched by the selector, DOM node, or jQuery object passed. ```csharp var selector = new JQuerySelector("div").NextUntil(".class"); ``` ## Not Remove elements from the set of matched elements. ```csharp var selector = new JQuerySelector("div").Not(".class"); ``` ## OffsetParent Get the closest ancestor element that is positioned. ```csharp var selector = new JQuerySelector("div").OffsetParent(); ``` ## Parent Get the parent of each element in the current set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Parent(); ``` ## Parents Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Parents(); ``` ## ParentsUntil Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector, DOM node, or jQuery object. ```csharp var selector = new JQuerySelector("div").ParentsUntil("body"); ``` ## Prev Get the immediately preceding sibling of each element in the set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Prev("div"); ``` ## PrevAll Get all preceding siblings of each element in the set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").PrevAll("div"); ``` ## PrevUntil Get all preceding siblings of each element up to but not including the element matched by the selector, DOM node, or jQuery object. ```csharp var selector = new JQuerySelector("div").PrevUntil(".class"); ``` ## Siblings Get the siblings of each element in the set of matched elements, optionally filtered by a selector. ```csharp var selector = new JQuerySelector("div").Siblings(); ``` ## Slice Reduce the set of matched elements to a subset specified by a range of indexes. ```csharp var selector = new JQuerySelector("div").Slice(1, 3); ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
