我们都知道,在excel中有众多模板可以供选择。是不是很眼馋?想不想将把这个功能加到我们自己的编辑器中呢?
答案是可以的
下面是我们实现的效果,是不是有模有样?那我们来看下这个是如何实现的吧。
我们知道(不知道的看下前面的文章),编辑器左上角这个“文件”按钮点开之后会是一个特别大的Template,那么想要往里加东西,就需要先获取这个Template,然后按照里面的结构去添加,添加完成之后再注册回去。我们新增的Template是下面这样的一个结构。这个会在附件的custom-file-menu-panel.js文件中,记住这个“custom_item_action_1”bindingPath。
var listDisplayContainer =
template["content"][0]["children"][0]["children"][1];
// 增加按钮
listDisplayContainer.children.push({
type: "Container",
visibleWhen: "activeCategory_main=CustomItem",
children: [
{
type: "TextBlock",
margin: "50px 0 15px 50px",
text: "自定义行为",
style: "font-size:36px;line-height:80px",
},
{
type: "ColumnSet",
margin: "0 0 0 50px",
children: [
{
type: "Column",
children: [
{
type: "List",
className: "file-menu-list",
items: [
{
text: "打印",
value: "print",
},
{
text: "加载模板",
value: "action_1",
},
],
bindingPath: "custom_item",
},
],
width: "350px",
},
{
type: "Container",
children: [
{
type: "Button",
margin: "20px 50px",
text: "打印",
width: 200,
height: 200,
iconClass: "icon-common1 icon-print",
bindingPath: "custom_item_print",
iconPosition: "top",
},
],
visibleWhen: "custom_item=print",
},
{
type: "Container",
children: [
{
type: "Button",
margin: "20px 50px",
text: "编辑器模板",
width: 200,
height: 200,
iconClass: "icon-common1 icon-tmp",
bindingPath: "custom_item_action_1",
iconPosition: "top",
},
],
visibleWhen: "custom_item=action_1",
}
],
},
],
});
上面的图片是怎么加进去的呢?就是通过iconClass将对应的css引入。其余大家可以通过下面的代码进行研究
.icon-tmp {
/* 背景图片 */
background-image: url("./jsonPic.png");
}
.icon-print {
/* 打印的背景图片 */
background-image: url("./print.png");
}
.icon-common1 {
width: 150px;
height: 150px;
}
设计完模板之后,我们就需要重写下面的这个命令了
GC.Spread.Sheets.Designer.getCommand(GC.Spread.Sheets.Designer.CommandNames.FileMenuPanel);
通过重写execute方法,在里面判断对应的bindingPath是否一致,一致则进到这个case里面包我想要的模板加载或者逻辑添加即可。
var fileMenuPanelCommand = GC.Spread.Sheets.Designer.getCommand(GC.Spread.Sheets.Designer.CommandNames.FileMenuPanel);// 获取文件按钮表盘
var oldExecuteFn = fileMenuPanelCommand.execute;// 执行按钮获取
// 重写执行逻辑
fileMenuPanelCommand.execute = function (context, propertyName, newValue) {
// console.log(context)
// console.log(propertyName)
// console.log(newValue)
oldExecuteFn.apply(this, arguments);
switch (propertyName) {
case 'custom_item_print':// 自定义打印
var workbook = context.getWorkbook();// context就是designer
workbook.print();// 打印
break;
case 'custom_item_action_1':// 自定义行为1
var workbook = context.getWorkbook();
workbook.fromJSON(tmp)// 导入设定好的模板
GC.Spread.Sheets.Designer.getCommand('fileMenuPanel').execute(designer, "activeCategory_hide", true)// 执行指令
break;
}
}
最后,别忘了将新的模板和命令注册回去。
var config = GC.Spread.Sheets.Designer.DefaultConfig;
config.commandMap = {
fileMenuPanel: fileMenuPanelCommand
}
var designer = new GC.Spread.Sheets.Designer.Designer("gc-designer-container", config);
