您可以使用四种类型的剪贴板事件,如 ClipboardChanged 、 ClipboardChanging 、 ClipboardPasted 和 ClipboardPasting 事件。
ClipboardChanged和ClipboardChanging事件分别在剪贴板发生变更和剪贴板正在变更时发生。类似地,clipboardpaste和ClipboardPasting事件分别发生在用户从剪贴板粘贴时和用户正在粘贴时。通过这些剪贴板事件,用户可以对Excel中的文本、单元格数据、图片、图表、形状、切片器和自定义浮动对象执行复制粘贴操作,也可以在表单内部和表单之间执行复制粘贴操作。
Currently, cut or copy operations from SpreadJS to Excel is not supported.
本示例使用了不同的剪贴板事件。
<script>
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
//获取活动表
var activeSheet = spread.getActiveSheet();
// 将allowCopyPasteExcelStyle设置为true
spread.options.allowCopyPasteExcelStyle = true;
// 剪贴板事件绑定
activeSheet.bind(GC.Spread.Sheets.Events.ClipboardChanged, function (sender, args) {
console.log("ClipboardChanged.");
});
activeSheet.bind(GC.Spread.Sheets.Events.ClipboardChanging, function (sender, args) {
console.log("ClipboardChanging");
});
activeSheet.bind(GC.Spread.Sheets.Events.ClipboardPasted, function (sender, args) {
console.log("ClipboardPasted");
});
activeSheet.bind(GC.Spread.Sheets.Events.ClipboardPasting, function (sender, args) {
console.log("ClipboardPasting");
});
});
</script>
您可以在以下用例中使用剪贴板事件。
复制粘贴从Excel到SpreadJS
假设你有多个对象,如图像,图表和形状在Excel中,你想复制和粘贴所有对象,除了图像。为此,“cancel”参数在ClipboardPasting事件设置为真。
注意,为了将图像、图表和形状等对象从Excel复制粘贴到扩展表单中,需要将“allowCopyPasteExcelStyle”属性设置为true。要了解更多关于复制Excel对象的内容,请参考本主题。
下面的代码片段描述了如何防止图像副本从Excel扩展。
<script>
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
//获取活动表
var activeSheet = spread.getActiveSheet();
// 将allowCopyPasteExcelStyle设置为true
spread.options.allowCopyPasteExcelStyle = true;
// 添加图片
activeSheet.pictures.add("f2", "Capture.PNG", 100, 60, 200, 100);
// 这段代码防止将图像从Excel复制到SpreadJS
spread.bind(GC.Spread.Sheets.Events.ClipboardPasting, (e, args) => {
if ((args.pasteData && args.pasteData.image)) {
args.cancel = true;
}
});
});
</script>
SpreadJS表单复制粘贴
假设您在SpreadJS中有多个对象,比如图像、图表和形状,并且您想要复制粘贴SpreadJS中除了图像以外的所有浮动对象。剪贴板事件中的“objects”参数可用于复制粘贴文本、单元格数据、图片、自定义浮动对象、切片器、图表和形状。下面的代码片段描述了如何通过将“cancel”参数设置为true来防止在扩展表单中复制图像。
<script>
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
//获取活动表
var activeSheet = spread.getActiveSheet();
// 将allowCopyPasteExcelStyle设置为true
spread.options.allowCopyPasteExcelStyle = true;
spread.bind(GC.Spread.Sheets.Events.ClipboardPasting, (e, args) => {
// 这段代码防止内部浮动元素复制粘贴//这段代码防止外部图像粘贴
if ((args.objects && args.objects.length > 0) || (args.pasteData && args.pasteData.image)) {
//alert("test");
args.cancel = true;
}
});
});
</script>
