In this blog I would like to share the code to add the custom fields on SharePoint host web list using SharePoint hosted app.

 

In *.aspx page add HTML Button

 

<button type="button" id="btnCreate">Add Field</button>

 

Write below code on *.js file,

//get Current Context
var context = SP.ClientContext.get_current();
// This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function () {
console.log("page loading...");
$("#btnCreate").click(function () {
addField();
});
});

//this method is used to add the fields on custom list
function addField() {
//Get host web URL
var hostWebUrl = decodeURIComponent(manageQueryStringParameter('SPHostUrl'));
//get app context using host web url
var appCtxSite = new SP.AppContextSite(context, hostWebUrl);
//get current web
var currentWEB = appCtxSite.get_web();
//get list from host web
var list = currentWEB.get_lists();
//load the list
context.load(list);
context.executeQueryAsync(function () {
//get custom list by name
var currentList = list.getByTitle("sampleList");
//get field collection from current list
var fldCollection = currentList.get_fields();
//set the type and field details
var f1 = context.castTo(fldCollection.addFieldAsXml('<Field Type="Text" DisplayName="Person Name" Name="PersonName" />', true, SP.AddFieldOptions.addToDefaultContentType), SP.FieldText);
f1.set_title("PersonName");
//update
f1.update();
context.executeQueryAsync(function () {
console.log("Field Creation Success");
},

function (sender, args) {
console.log("Field Creation failed : " + args.get_message());
});
}, function (sender, args) {
onfail(sender, args);
});
}

// This function is executed if the above call fails
function onfail(sender, args) {
alert('Failed to add field in list. Error:' + args.get_message());
}

// this method used split the query string
function manageQueryStringParameter(paramToRetrieve) {
var params = document.URL.split("?")[1].split("&");
var strParams = "";
for (var i = 0; i < params.length; i = i + 1) {
var singleParam = params[i].split("=");
if (singleParam[0] == paramToRetrieve) {
return singleParam[1];
}
}
}

Note - In app manifest file provide full control permission to the web as shown in below,
