Reorder HTML table rows using drag-and-drop

Question

I have a jQuery function to move table rows up and down  I do not know how to save the data  nor get the position of each row  I am using PHP to show the table rows   How do I get each table row position value when the user reorders the table rows

The jQuery UI sortable plugin provides drag-and-drop reordering  A save button can extract the IDs of each item to create a comma-delimited string of those IDs  added to a hidden textbox  The textbox is returned to the server using an async postback   This fiddle example reorders table elements  but does not save them to a database   The sortable plugin takes one line of code to turn any list into a sortable list  If you care to use them  it also provides CSS and images to provide a visual impact to sortable list  see the example that I linked to   Developers  however  must provide code to retrieve items in their new order  I embed unique IDs of each item in the list as an HTML attribute and then retrieve those IDs via jQuery   For example      ----- code executed when the document loads   function         wireReorderList         function wireReorderList             reorderExampleItems   sortable            reorderExampleItems   disableSelection       function saveOrderClick            ----- Retrieve the li items inside our sortable list     var items       reorderExampleItems li         var linkIDs    items size         var index   0          ----- Iterate through each li  extracting the ID embedded as an attribute     items each          function intIndex                linkIDs index      this  attr  ExampleItemID                index                      get   lt   txtExampleItemsOrder ClientID   gt    value   linkIDs join

thanks to Jim Petkus  that did gave me a wonderful answer    but i was trying to solve my own script not to changing it to another plugin   My main focus was not using an independent plugin and do what i wanted  just by using the jquery core    and guess what i did find the problem    var title      em   attr  title       div   text title     this is what i add to my script  and  the blew codes to my html part      lt td gt   lt em title    weight   gt  weight lt  em gt  lt  td gt    and found each  row  weight value   thanks again to  Jim Petkus

Apparently the question poorly describes the OP s problem  but this question is the top search result for dragging to reorder table rows  so that is what I will answer  I wasn t interested in bringing in jQuery UI for something so simple  so here is a jQuery only solution   x000D   x000D      grab   mousedown function e      var tr     e target  closest  TR        si   tr index        sy   e pageY      b     document body       drag    if  si    0  return    b addClass  grabCursor   css  userSelect    none      tr addClass  grabbed       function move e        if   drag  amp  amp  Math abs e pageY - sy   lt  10  return      drag   true      tr siblings   each function           var s     this           i   s index            y   s offset   top        if  i  gt  0  amp  amp  e pageY  gt   y  amp  amp  e pageY  lt  y   s outerHeight              if  i  lt  tr index              tr insertAfter s           else           tr insertBefore s           return false                         function up e        if  drag  amp  amp  si    tr index            drag   false        alert  moved                 document  unbind  mousemove   move  unbind  mouseup   up       b removeClass  grabCursor   css  userSelect    none        tr removeClass  grabbed            document  mousemove move  mouseup up       x000D   grab     cursor  grab      grabbed     box-shadow  0 0 13px  000      grabCursor   grabCursor       cursor  grabbing  important    x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt   lt table gt     lt tr gt       lt th gt  lt  th gt       lt th gt Table Header lt  th gt     lt  tr gt     lt tr gt       lt td class  grab  gt  amp  9776  lt  td gt       lt td gt Table Cell 1 lt  td gt     lt  tr gt     lt tr gt       lt td class  grab  gt  amp  9776  lt  td gt       lt td gt Table Cell 2 lt  td gt     lt  tr gt     lt tr gt       lt td class  grab  gt  amp  9776  lt  td gt       lt td gt Table Cell 3 lt  td gt     lt  tr gt   lt  table gt  x000D   x000D   x000D   Note si    0 and i  gt  0 ignores the first row  which for me contains TH tags  Replace the alert with your  quot drag finished quot  logic
