The selector   nr first  is specifically looking for the first  and only the first  element having class  nr  within the selected table element  If you instead call  find   nr   you will get all of the elements within the table having class  nr   Once you have all of those elements  you could use the  each method to iterate over them  For example       use-address   click function             choose-address-table   find   nr   each function i  nrElt            var id   nrElt text                resultas   append   lt p gt     id     lt  p gt        Testing  append the contents of the td to a div               However  that would get you all of the td nr elements in the table  not just the one in the row that was clicked  To further limit your selection to the row containing the clicked button  use the  closest method  like so       use-address   click function           this  closest  tr   find   nr   each function i  nrElt            var id   nrElt text                resultas   append   lt p gt     id     lt  p gt        Testing  append the contents of the td to a div

Try this       use-address   click function          this  closest  tr   find  td   each function             var textval     this  text       this will be the text of each  lt td gt               This will find the closest tr  going up through the DOM  of the currently clicked button and then loop each td - you might want to create a string   array with the values   Example here  Getting the full address using an array example here

The object of the exercise is to find the row that contains the information  When we get there  we can easily extract the required information   Answer      use-address   click function         var  item     this  closest  tr        Finds the closest row  lt tr gt                           find   nr          Gets a descendent with class  nr                          text               Retrieves the text within  lt td gt           resultas   append  item            Outputs the answer       VIEW DEMO  Now let s focus on some frequently asked questions in such situations   How to find the closest row   Using  closest     var  row     this  closest  tr      Using  parent     You can also move up the DOM tree using  parent   method  This is just an alternative that is sometimes used together with  prev   and  next     var  row     this  parent                  Moves up from  lt button gt  to  lt td gt                     parent                  Moves up from  lt td gt  to  lt tr gt    Getting all table cell  lt td gt  values  So we have our  row and we would like to output table cell text   var  row     this  closest  tr             Finds the closest row  lt tr gt        tds    row find  td                   Finds all children  lt td gt  elements    each  tds  function                      Visits every single  lt td gt  element     console log   this  text               Prints out the text within the  lt td gt        VIEW DEMO  Getting a specific  lt td gt  value  Similar to the previous one  however we can specify the index of the child  lt td gt  element   var  row     this  closest  tr              Finds the closest row  lt tr gt        tds    row find  td nth-child 2        Finds the 2nd  lt td gt  element    each  tds  function                       Visits every single  lt td gt  element     console log   this  text                Prints out the text within the  lt td gt        VIEW DEMO  Useful methods    closest   - get the first element that matches the selector  parent   - get the parent of each element in the current set of matched elements  parents   - get the ancestors of each element in the current set of matched elements  children   - get the children of each element in the set of matched elements  siblings   - get the siblings of each element in the set of matched elements  find   - get the descendants of each element in the current set of matched elements  next   - get the immediately following sibling of each element in the set of matched elements  prev   - get the immediately preceding sibling of each element in the set of matched elements
