Using jQuery to implement a simple editable table based on Bootstrap_javascript skills

editTable.js Provides operations for editing the current row of the table, adding a row, and deleting the current row. Parameters can be set, such as:

operatePos is used to set the column of the placement operation, starting from 0, -1 means using the last column as the column of the placement operation; (Operations here include editing the current row, adding a row under the current row, and deleting the current row)

handleFirst sets whether the first row of the table is used as the object of the operation, true is true, false is false;

edit, save, cancel, add, confirm and del respectively set the operation name of the display operation. By default, the words "edit", "save", "cancel", "add", "confirm" and "delete" are displayed;

editableCols sets the columns that can be edited, starting from 0, and is set in the form of an array, such as [1, 2], which means that the 2nd and 3rd columns can be edited when editing operations are performed; you can pass in "all", Indicates that all selected columns can be edited; of course, the program will automatically exclude columns that have been set to place operations;

order sets the operations required for the table, and can also set the order in which operations are arranged; the parameters are in the form of an array, and the values ​​in the array can be edit, add, or del; if an empty array is passed in, the edit operation will be provided by default, which is equivalent to setting [ "edit" ] parameter; in addition, all functions are provided by default, that is, editing, adding, and deleting, which is equivalent to setting the [ "edit", "add", "del"] parameters, and the order is edit-》add-》delete; it is possible Modify the order of the three, such as [ "add", "edit", "del" ];

saveCallback When the editing function is provided, during the process of editing the current row, click the callback function after saving; the user needs to set this parameter while using the editing function. When saving, the function can be passed using ajax Edited data data (saved in the data array), when ajax saves the data successfully, you should also call the isSuccess method in the function parameters to change the editable state in the interface to the uneditable state;

addCallback and delCallback are the same as saveCallback, but they are applied to different operations - add and delete.

You need to pay attention during use: you need to add selectable selectors to the corresponding table, and you need to place an empty label in the column where the "operation" is placed for storing the "operation" ".
