Custom context menus for GridJs

Custom build-in context menus

We have some build in context menu items ,for example insert/delete row/column and so on. for example:to delete “Delete row”,“Link”,“Hide” menu items in context menus,assume the div id of GridJs is “gridjs-divid”

   //get context menus parent dom
   const menus=document.querySelector("#gridjs-divid > div > div.x-spreadsheet-sheet > div.x-spreadsheet-contextmenu");
   var childs = menus.childNodes;
   for (var i = childs.length - 1; i >= 0; i--)
   {  
     // check the item text
     if(childs[i].childNodes[0]?.textContent==="Delete row"||childs[i].childNodes[0]?.textContent==="Link"||childs[i].childNodes[0]?.textContent==="Hide")
       {
         menus.removeChild(childs[i]);
       }
   }

After call this function

Custom self-defined context menus

We have some build in context menu items ,for example insert/delete row/column and so on. However if user want to custom context menu items. We support set context menu items in load options. for example:

        const onMyActionClick1 = (sheet) => {
            console.log('my action clicked1' +  sheet.data.name)
        };
        const onMyActionClick2 = (sheet) => {
            console.log('my action clicked2' + sheet.data.name)
        };
  xs = x_spreadsheet('#gridjs-demo', {
                updateMode: 'server',
                updateUrl: '/GridJs2/UpdateCell',
                showToolbar: true,
                mode: 'edit',
                local: 'en',
                showContextmenu: true,
		//this option is for context menus,we need to set usedefault to false to load custom context menus
                contextMenuItems: {
                    usedefault: false,
                    customItems: [{ 'key': 'key1', 'text': 'c title 11111', 'callback': onMyActionClick1 },
                                  { 'key': 'key2', 'text': 'c title 22222', 'callback': onMyActionClick2 }]
                }
            })

We support the below JS APIs for custom context menu items at runtime

• get custom context menu items

xs.sheet.getCustomContextMenuItems()

• add custom context menu items

xs.sheet.addCustomContextMenuItems(itemsarray)
 // the parameter is:
 itemsarray: the array of custom menu items,the callback function x parameter will be the js variable of xs.sheet
 for example: [{'key':'key4','text':'menu4','callback':(x)=>{console.log('hello4444');}},{'key':'key3','text':'menu3','callback':(x)=>{console.log('hello3333');}}]

• delete custom context menu items

 xs.sheet.delCustomContextMenuItems(keysarray)()
 // the parameter is:
 keysarray: the array of the keys of the menu items
 for example: ['key4','key3']

• insert custom context menu item at specified postion

xs.sheet.insertCustomContextMenuItem(item,postion)
 // the parameter is:
 item: the custom menu item,the callback function x parameter will be the js variable of xs.sheet
 for example: {'key':'key4','text':'menu4','callback':(x)=>{console.log('hello4444');}} 
 postion:the postion for the inserted item in the items array

• update custom context menu item by the key

xs.sheet.updateCustomContextMenuItem(key,item)
 // the parameter is:
 item: the updated properties that with text or callback
 for example: {'text':'menu updated'}
 key:the key of the menu item

• get custom context menu items for image/shape

xs.sheet.getImageContextMenuItems()

• add custom context menu items for image/shape

xs.sheet.addImageContextMenuItems(itemsarray)
 // the parameter is:
 itemsarray: the array of custom menu items,the callback function x parameter will be the js variable of xs.sheet
 for example: [{'key':'key4','text':'img operation1','callback':(x)=>{console.log('operation1 on image');}},{'key':'key3','text':'img operation2','callback':(x)=>{console.log('operation2 on image');}}]

• delete custom context menu items for image/shape

 xs.sheet.delImageContextMenuItems(keysarray)()
 // the parameter is:
 keysarray: the array of the keys of the menu items
 for example: ['key4','key3']
