These methods get and set DOM attributes of elements. These methods get and set css related properties of elements. finding ancestors, descendants or sibling element of a specified element. ![]() The example you posted above (taken from the jQuery API page for add() ) adds a red border to the collection of 6 existing DIVs on the page, then adds the 'p' element on the page to the collection and turns all 7 backgrounds yellow. These methods help in navigating from DOM element to another element in a parent child hierarchy e.g. The jQuery add() method adds existing DOM elements to an existing jQuery object. changing attribute, style attribute, adding and removing elements etc. For example, you might have a code element that you want to wrap in a pre: $( 'code#n1').These methods manipulate DOM elements in some manner e.g. This is quite a rare use case, but you might want to enclose an existing element in a new one. You can swap an existing element for a newly-created one using the replaceWith() method: $( '#old').replaceWith( "New paragraph") Wrap Around an Existing Element This is a good choice if, for example, you want to add a new paragraph in the middle of two others. (selector).append(content,function(index,html)). Add It as the Sibling of an Existing Element $( "p.last").after( "A new paragraph") Tip: To insert content at the beginning of the selected elements, use the prepend() method. You can use this method, for example, to add a new list item at the end of a list. Add as the Child of an Existing Element $( "body").append($( "Hello, world")) The jQuery documentation gathers these methods together under the ‘manipulation’ category. before () - Inserts content before the selected elements. after () - Inserts content after the selected elements. add() method constructs a new jQuery object from the union of those elements and the ones. prepend () - Inserts content at the beginning of the selected elements.

The INPUT element is used to create a hidden control. ('mainTable tbody'). This returns a special jQuery object which contains a collection of elements. Just in case if row is too complex, what I do is, keep first row hidden with required structure, make a clone and modify text and insert after first row, this way if you fetch data from ajax response your table will be created, remember clone it outside the loop, then use it to modify content inside loop. The items have ids derived strictly from the name. When you pass a string containing HTML as the first parameter, this function will create a new element: $( "") Each row contains a label, an input field, and an optional third column.
