Arbeiten mit GridJs auf der Clientseite

Wir haben GridJs auf der Clientseite basierend auf x-spreadsheet entwickelt.

Die Hauptschritte sind:

Erstellen einer x_spreadsheet-Instanz

xs = x_spreadsheet(id, options)
    // the parameters are:
    id:the html node id ,for example :'#gridjs-demo' for the html  <div id="gridjs-demo"></div>
    options:the load options,
     // the parameters for options:
	    updateMode:  currently we only support 'server'
	    updateUrl:  set the server side  url for update action based on json
	    mode: read means readonly spread sheet/edit means we can edit the spread sheet
            allowSelectTextInTextBoxInReadMode: whether allow select text in TextBox control when in read mode,the default value is false
	    showToolbar:   means whether to show toolbar
	    showFileName:  whether to show the filename 
	    local:         support multiple language for menus ,the locale can be:
	                        en, cn, es, pt, de, ru, nl, 
	                   for  English,Chinese,Spanish,Portuguese,German,Russian,Dutch
			        ar, fr,id,it,ja
                           for  Arabic,French,Indonesian,Italian,Japanese
			        ko,th,tr,vi,cht
                           for  Korean,Thai,Turkey,Vietnamese,Traditional Chinese                  
	    showContextmenu:   means whether to show contextmenu on right click on a cell
            loadingGif:  the loading gif url when loading the image/shape .it is optional,the default value is:content/img/updating.gif
	for example the below code init a x_spreadsheet object.
	xs = x_spreadsheet('#gridjs-demo', {
			updateMode:'server',
			updateUrl:'/GridJs2/UpdateCell',
			mode: 'edit',
			showToolbar: true,
                        local: 'en',
			showContextmenu: true
			})

Laden mit JSON-Daten

Informationen für Form/Bilder-Bearbeitung für serverseitige Aktion festlegen

xs.setImageInfo(imageGetActionUrl, imageAddByUploadActionUrl, imageAddByUrlActionUrl, imageCopyActionUrl, zindex, loadingGif);
// the parameters are:
	imageGetActionUrl: the get image action URL in the server side controller
	imageAddByUploadActionUrl: the upload image action  URL in the server side controller
	imageAddByUrlActionUrl: the add image from URL action  URL in the server side controller
	imageCopyActionUrl: the copy image action  URL in the server side controller
	zindex: the minimum zindex of the image in the canvas
	loadingGif (optional): the loading gif url when loading the image/shape .it is optional,the default value is:content/img/updating.gif
    for example: 
            const imageurl = "/GridJs2/imageurl";
            const imageuploadurl1 = "/GridJs2/AddImage";
            const imageuploadurl2 = "/GridJs2/AddImageByURL";
            const imagecopyurl = "/GridJs2/CopyImage";  
	    const basiczorder = 5678;
    xs.setImageInfo(imageurl, imageuploadurl1, imageuploadurl2, imagecopyurl, basiczorder);

Informationen für Download-Bearbeitung für serverseitige Aktion festlegen

xs.setFileDownloadInfo(downloadActionUrl);
// the parameters are:
	downloadActionUrl: the get download file action URL in the server side controller

    for example: 
            const fileDownloadUrl = "/GridJs2/Download";
            xs.setFileDownloadInfo(fileDownloadUrl);

Informationen für OLE-Objekt-Bearbeitung für serverseitige Aktion festlegen

xs.setOleDownloadInfo(oleActionUrl);
// the parameters are:
	oleActionUrl: the ole object file action URL in the server side controller
    for example: 
            const oleDownloadUrl = "/GridJs2/Ole";
            xs.setOleDownloadInfo(oleDownloadUrl);
