禁用右键菜单

问题:SpreadJS如何禁用右键菜单


背景:

对于一些仅需要浏览,不需要操作的场景,例如报表展示,可以通过下面的方式来禁用右键菜单,避免使用者通过右键菜单进行操作。

解决方案:

allowContextMenu 表示 SpreadJS 或 designer 右键菜单是否可用。

使用使用下方代码查看 SpreadJS 或 designer 的右键菜单可用状态:

spread.options.allowContextMenu;

如下示例:

image

使用下方代码允许SpreadJS 或 designer 的右键菜单可用:

spread.options.allowContextMenu = true;

使用下方代码禁用SpreadJS 或 designer 的右键菜单:

spread.options.allowContextMenu = false;

在线表格编辑器如何禁用右键菜单?

解决方案:

在线表格编辑器,它的右键菜单相关的结构如下:

image

可以看到,它并没有显示区域workArea的标记。这是因为设计器中的右键菜单是根据配置信息动态处理而来。如果想修改设计器的右键菜单,需要从GC.Spread.Sheets.Designer.DefaultConfig中去更改.

image

如上图所示,config中的contextMenu代表的就是右键菜单命令字符串,调用GC.Spread.Sheets.Designer.getCommand("contextMenuCut")可以得到命令的详细信息,其中visibleContex代表的就是右键菜单显示的条件。

image

如果想要禁用工作表页签处的右键菜单,只需将visibleContext中包含“TabStripSelected”的数组项删除即可

let config = GC.Spread.Sheets.Designer.DefaultConfig
for(let i=0;i<config.contextMenu.length;i++){
    if(GC.Spread.Sheets.Designer.getCommand(config.contextMenu[i]).visibleContext && GC.Spread.Sheets.Designer.getCommand(config.contextMenu[i]).visibleContext.indexOf("TabStripSelected")!=-1){
        config.contextMenu.splice(i,1)
        i--
    }
}

let designer = new GC.Spread.Sheets.Designer.Designer("designer-container",config)
