Add-in Code Snippet

The following code snippet is used in SharePoint Add-in to add a new web part to the Site Pages library in target SharePoint site.

[code language=”javascript”]

// Load the js files and continue to the successHandler
$.getScript(scriptbase + "SP.RequestExecutor.js", execCrossDomainRequest);

// Function to prepare and issue the request to get
// SharePoint data
function execCrossDomainRequest() {
// Initialize the RequestExecutor with the add-in web URL.
var executor = new SP.RequestExecutor(appweburl);
// Issue the call against the add-in web.
// To add webpart page, use tempaltefiletype=0 in addtemplatefile method using REST we can hit the endpoint:
// The response formats the data in the JSON format.
executor.executeAsync({
url: appweburl + "/_api/SP.AppContextSite(@target)/web/getfolderbyserverrelativeurl(‘/SitePages’)/files/addtemplatefile(urloffile=’/SitePages/newwebpartpage.aspx’,templatefiletype=0)&@target=’" + hostweburl + "’",
method: "POST",
data: JSON.stringify(data),
headers: {
"Accept": "application/json; odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val()
},
success: successHandler,
error: errorHandler
});
}
// Function to handle the success event.
function successHandler(data) {
console.log(‘File created successfully!’)
alert(‘File created successfully!’);
}

function errorHandler(data, errorCode, errorMessage) {
