Using Javascript how to store previous search history in browser

I have implemented autocomplete feature using JQuery, but now I wanted to store last 20 searched per inputfield in browser. So, if user when focuses the suggestion will be fetched from the browser. If user types then from Rest API using ajax I am fetching the data.
$("input[type='text']").autocomplete({
source: function(request, response) {
var id = $(this.element).prop("id");
var id2=this.element[0].id;
var id3=$(this.element.get(0)).attr('id');
console.log(id);
console.log(id2);
console.log(id3);
var params = {'page':1,'size':"10"};
params[id]=request.term;
var jsonParams = JSON.stringify(params);
$.ajax({
type: "POST",
url:"http://localhost:5645/search",
data: jsonParams,
headers: {"X-CSRF-TOKEN": $("input[name='_csrf']").val()},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
//const result = new Set()
var result=[];
console.log(id);
console.log(msg.details)
console.log(msg.details.length)
for(var i = 0; i < msg.details.length; i++) {
var obj = msg.details[i];
if(obj!=null && columnMapping[id]!=undefined && obj[columnMapping[id]]!=undefined){
console.log(obj[columnMapping[id]]);
//result.add(obj[columnMapping[id]]);
result.push(obj[columnMapping[id]]);
}
console.log(result);
}
//response(Array.from(result));
response(result);
}
/* error: function() {
response([]);
} */
})
},
select: function(event, ui) {
alert(ui.item ? ("You picked '" + ui.item.label) : "Nothing selected, input was " + this.value);
return false;
}
}).autocomplete("instance")._renderItem = function(ul, item) {
console.log('test');
var item = $("<div>" + item.label + "</div>")
return $("<li>").append(item).appendTo(ul);
};
Above is the jquery code which I am using for autocomplete. So, if no input is there I need to fetch from browser recent search. So, when user types unique search keys should be inserted. How I can store and retrive using javascript.

WordPress REST API Ajax show more posts button

PHP/HTML:
<ul id="load-more-div"></ul>
<a id="load-more" data-ppp="<?php echo get_option('posts_per_page'); ?>">load more</a>
JavaScripts:
(function($) {
// Grab the load more button, since I only want to run the code if the button is on the page
var loadMoreButton = $("#load-more");
if (loadMoreButton) {
// Get the posts_per_page number set in Reading Options
var ppp = loadMoreButton.data("ppp");
// Initialize function
var loadPosts = function(page) {
var theData, loadMoreContainer, errorStatus, errorMessage;
// The AJAX request
$.ajax({
url: "/wp-json/wp/v2/posts",
dataType: "json",
data: {
// Match the query that was already run on the page
per_page: ppp,
page: page,
type: "post",
orderby: "date"
},
success: function(data) {
// Remove the button if the response returns no items
if (data.length < 1) {
loadMoreButton.remove();
}
// Create a place to store exactly what I need
// Alternatively, the response can be filtered to only return the needed data, which is probably more efficient as the following loop wont be needed
theData = [];
// Get only what I need, and store it
for (i = 0; i < data.length; i++) {
theData[i] = {};
theData[i].id = data[i].id;
theData[i].link = data[i].link;
theData[i].title = data[i].title.rendered;
theData[i].content = data[i].content.rendered;
}
// Grab the container where my data will be inserted
loadMoreContainer = $("#load-more-div");
// For each object in my newly formed array, build a new element to store that data, and insert it into the DOM
$.each(theData, function(i) {
loadMoreContainer.append(
'<li><a href="' +
theData[i].link +
'">' +
theData[i].title +
"</a></li>"
);
});
},
error: function(jqXHR, textStatus, errorThrown) {
errorStatus = jqXHR.status + " " + jqXHR.statusText + "\n";
errorMessage = jqXHR.responseJSON.message;
// Show me what the error was
console.log(errorStatus + errorMessage);
}
});
};
// Since our AJAX query is the same as the original query on the page (page 1), start with page 2
var getPage = 2;
// Actually implement the functionality when the button is clicked
loadMoreButton.on("click", function() {
loadPosts(getPage);
// Increment the page, so on the next click we get the next page of results
getPage++;
});
}
})(jQuery);
This is the trouble part, it doesn't remove the link.
// Remove the button if the response returns no items
if (data.length < 1) {
loadMoreButton.remove();
}
Console errors when click the load more link after reaching the end of posts:
400 Bad Request The page number requested is larger than the number of pages available.

I found two ways to solve it:
###Using data attribute
Get the max number of pages in the template, assign it to a data attribute, and access it in the scripts. Then check current page against total page numbers, and set disabled states to the load more button when it reaches the last page.
PHP/HTML:
<ul id="ajax-content"></ul>
<button type="button" id="ajax-button" data-endpoint="<?php echo get_rest_url(null, 'wp/v2/posts'); ?>" data-ppp="<?php echo get_option('posts_per_page'); ?>" data-pages="<?php echo $wp_query->max_num_pages; ?>">Show more</button>
JavaScripts:
(function($) {
var loadMoreButton = $('#ajax-button');
var loadMoreContainer = $('#ajax-content');
if (loadMoreButton) {
var endpoint = loadMoreButton.data('endpoint');
var ppp = loadMoreButton.data('ppp');
var pages = loadMoreButton.data('pages');
var loadPosts = function(page) {
var theData, errorStatus, errorMessage;
$.ajax({
url: endpoint,
dataType: 'json',
data: {
per_page: ppp,
page: page,
type: 'post',
orderby: 'date'
},
beforeSend: function() {
loadMoreButton.attr('disabled', true);
},
success: function(data) {
theData = [];
for (i = 0; i < data.length; i++) {
theData[i] = {};
theData[i].id = data[i].id;
theData[i].link = data[i].link;
theData[i].title = data[i].title.rendered;
theData[i].content = data[i].content.rendered;
}
$.each(theData, function(i) {
loadMoreContainer.append('<li>' + theData[i].title + '</li>');
});
loadMoreButton.attr('disabled', false);
if (getPage == pages) {
loadMoreButton.attr('disabled', true);
}
getPage++;
},
error: function(jqXHR) {
errorStatus = jqXHR.status + ' ' + jqXHR.statusText + '\n';
errorMessage = jqXHR.responseJSON.message;
console.log(errorStatus + errorMessage);
}
});
};
var getPage = 2;
loadMoreButton.on('click', function() {
loadPosts(getPage);
});
}
})(jQuery);
###Using jQuery complete event
Get the total pages x-wp-totalpages from the HTTP response headers. Then change the button states when reaches last page.
PHP/HTML:
<ul id="ajax-content"></ul>
<button type="button" id="ajax-button" data-endpoint="<?php echo get_rest_url(null, 'wp/v2/posts'); ?>" data-ppp="<?php echo get_option('posts_per_page'); ?>">Show more</button>
JavaScripts:
(function($) {
var loadMoreButton = $('#ajax-button');
var loadMoreContainer = $('#ajax-content');
if (loadMoreButton) {
var endpoint = loadMoreButton.data('endpoint');
var ppp = loadMoreButton.data('ppp');
var pager = 0;
var loadPosts = function(page) {
var theData, errorStatus, errorMessage;
$.ajax({
url: endpoint,
dataType: 'json',
data: {
per_page: ppp,
page: page,
type: 'post',
orderby: 'date'
},
beforeSend: function() {
loadMoreButton.attr('disabled', true);
},
success: function(data) {
theData = [];
for (i = 0; i < data.length; i++) {
theData[i] = {};
theData[i].id = data[i].id;
theData[i].link = data[i].link;
theData[i].title = data[i].title.rendered;
theData[i].content = data[i].content.rendered;
}
$.each(theData, function(i) {
loadMoreContainer.append('<li>' + theData[i].title + '</li>');
});
loadMoreButton.attr('disabled', false);
},
error: function(jqXHR) {
errorStatus = jqXHR.status + ' ' + jqXHR.statusText + '\n';
errorMessage = jqXHR.responseJSON.message;
console.log(errorStatus + errorMessage);
},
complete: function(jqXHR) {
if (pager == 0) {
pager = jqXHR.getResponseHeader('x-wp-totalpages');
}
pager--;
if (pager == 1) {
loadMoreButton.attr('disabled', true);
}
}
});
};
var getPage = 2;
loadMoreButton.on('click', function() {
loadPosts(getPage);
getPage++;
});
}
})(jQuery);

The problem appears to be an invalid query to that endpoint so the success: function() is never being run in this circumstance.
Add to All API Errors
You could add the same functionality for all errors like this...
error: function(jqXHR, textStatus, errorThrown) {
loadMoreButton.remove();
....
}
Though that may not be the desired way of handling of all errors.
Test for Existing Error Message
Another option could be to remove the button if you receive an error with that exact message...
error: function(jqXHR, textStatus, errorThrown) {
if (jqXHR.statusText === 'The page number requested is larger than the number of pages available.') {
loadMoreButton.remove();
}
....
}
but this would be susceptible to breaking with any changes to that error message.
Return Custom Error Code from API
The recommended way to handle it would be to return specific error code (along with HTTP status code 400) to specify the exact situation in a more reliable format...
error: function(jqXHR, textStatus, errorThrown) {
if (jqXHR.statusCode === '215') {
loadMoreButton.remove();
}
....
}
Here's an example on how to configure error handling in an API: Best Practices for API Error Handling
Return 200 HTTP Status Code
The last option would be to change the way your API endpoint handles this type of "error"/situation, by returning a 200 level HTTP status code instead, which would invoke the success: instead of the error: callback instead.

Retrieving data from myapifilms.com api

I am following a tutorial on YouTube showing how to get data from the myapifilms.com api and I am having trouble rendering the data to HTML. Currently my ajax call is working and the data is showing in the console. The problem I am having is getting the data to show on the page itself. I searched through the question already asked but had no luck. Here's my js code so far:
$(document).ready(function(){
$("#searchMovie").click(searchMovie);
var movieTitle = $("#movieTitle");
var table = $("#results");
var tbody = $("#results tbody"); //table.find("tbody");
function searchMovie() {
var title = movieTitle.val();
$.ajax({
url: "http://www.myapifilms.com/imdb/idIMDB?title="+ title +"&token= + token goes here +&format=json&language=en-us&aka=0&business=0&seasons=0&seasonYear=0&technical=0&filter=2&exactFilter=0&limit=1&forceYear=0&trailers=0&movieTrivia=0&awards=0&moviePhotos=0&movieVideos=0&actors=0&biography=0&uniqueName=0&filmography=0&bornAndDead=0&starSign=0&actorActress=0&actorTrivia=0&similarMovies=0&adultSearch=0&goofs=0&quotes=0&fullSize=0&companyCredits=0",
dataType: "jsonp",
success: renderMovies
})
function renderMovies(movies) {
console.log(movies);
tbody.empty();
for(var m in movies) {
var movie = movies[m];
var title = movie.title;
var plot = movie.simplePlot;
var posterUrl = movie.urlPoster;
var imdbUrl = movie.urlIMDB;
var tr = $("<tr>");
var titleTd = $("<td>").append(title);
var plotTd = $("<td>").append(plot);
tr.append(titleTd);
tr.append(plotTd);
tbody.append(tr);
}
}
}
});
I feel like I am so close but can't quite figure what I am missing. Again I was following a tutorial so if there's a better way to accomplish this goal I'm definitely open to suggestions.
Update:
I changed my code to this and I'm getting undefined in the browser. I changed the for loop to this
success: function (movies) {
console.log(movies);
tbody.empty();
for (var m in movies) {
$(".movies").append("<h3>"+ movies[m].title +"</h3>");
$(".movies").append("<h3>"+ movies[m].plot +"</h3>");
}
}

I figured out a solution, instead of using myapifilms, I used the tmdb api instead. Changing my code to this worked:
var url = 'http://api.themoviedb.org/3/',
mode = 'search/movie?query=',
input,
movieName,
key = 'myapikey';
//Function to make get request when button is clicked to search
$('button').click(function() {
var input = $('#movie').val(),
movieName = encodeURI(input);
$.ajax({
type: 'GET',
url: url + mode + input + key,
async: false,
jsonpCallback: 'testing',
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
console.dir(json.results);
for (var i = 0; i < json.results.length; i++){
var result = json.results[i];
$(".moviesContainer").append('<div class="movies col-md-12">'+
'<img class="poster" src="http://image.tmdb.org/t/p/w500'+ result.poster_path +'" />'
+'<h3>'+ result.title +'</h3>'
+'<p><b>Overview: </b>'+ result.overview +'</p>'
+'<p><b>Release Date: </b>'+ result.release_date +'</p>'
+'</div>');
}
},
error: function(e) {
console.log(e.message);
}
});
});

How to update SharePoint 2010 Column with SharePoint Username via OnClick?

Good morning, I come to you guys looking for some assistance getting two functions to work. I think I'm almost there but I'm missing something. I cannot get the field in SharePoint to update but I can get my document to open no problem. Is something missing in the code below?
<script type="text/javascript">
function fnUpdateRecord(userId, id) {
$.getJSON("PROGRAM/_vti_bin/ListData.svc/List(" + id + ")?$select=ViewBy", function (data) {
var viewby = data.d.ViewBy;
var username = userId;
var doc = new Object();
doc.ViewBy = username;
$.ajax({
method: "POST",
url: "PROGRAM/_vti_bin/listdata.svc/List(" + id + ")",
contentType: "application/json; charset=utf-8",
processData: false,
beforeSend: beforeSendFunction,
data: JSON.stringify(doc),
dataType: "json",
error: function (xhr) {
alert(xhr.status + ": " + xhr.statusText);
},
success: function () {
}
});
});
}
function fnRecordAccess(id, path) {
$.ajax({
url: "GetCurrentUser.aspx",
context: document.body
}).success(function(result) {
var userId = $(result).find('.wtf').text()
fnUpdateRecord(userId, id);
window.open(path, "othrWn");
}).error(function(error) {
console.log(error);
});
}
</script>
I think call those functions via an OnClick:
onclick='fnRecordAccess(" + i.Id + ", "" + path + "")'><i class='fa fa-lg fa-pencil'></i> View</a>
I can get the item/infopath form to load in another window but it doesn't seem to run the function to add the username in the ViewBy column. Any ideas? Thank you for assisting!
Edit: Added fnCountrySearch; this calls the other functions.
function fnCountrySearch(choice) {
fnWaitDialog("show");
var searchId = choice;
$("#tableBody tr").remove();
$.getJSON("PROGRAM/_vti_bin/ListData.svc/List?$filter=Country eq '" + searchId + "'&$orderby=Name", function (data) {
var d = data.d;
if (d.results.length == 0) {
$("#noResultsAlert").show();
$("#notingQueried").hide();
}
else {
$.each(d.results, function (n, i) {
var path = i.Path + "/" + i.Name;
$("#tableBody").append("<tr><td>" + "<a class='btn btn-sm btn-default' class='pull-left' href='#' onclick='fnRecordAccess(" + i.Id + ", "" + path + "")'><i class='fa fa-lg fa-pencil'></i> View</a></td></tr>");
});
$("#noResultsAlert").hide();
$("#notingQueried").hide();
}
})
.always(function () {
fnWaitDialog("hide");
});
}
The beforeSendFunction:
function beforeSendFunction(xhr) {
// Manipulate headers for update
xhr.setRequestHeader("If-Match", "*");
// Using MERGE so that the entire entity doesn't need to be sent over the wire.
xhr.setRequestHeader("X-HTTP-Method", 'MERGE');
}

REST
To compare your code with published examples, you can refer to Microsoft's documentation of SharePoint 2010's REST interface here:
Data Access for Client Applications: Using the REST Interface
Reference Implementation: Client: Using the REST Interface from JavaScript
JSOM
SharePoint 2010 does have a JavaScript client object model that you can use as an alternative to the REST API. This can be an especially attractive option if you find yourself invoking the REST API via JavaScript, since the client object model does not require additional libraries.
If you were to rewrite your fnUpdateRecord method to use the JavaScript client object model it would look like this:
fnUpdateRecord(userId, id){
var listName = "List", fieldName = "ViewBy", newValue = userId + " # " + new Date() + ";\n";
var clientContext = new SP.ClientContext();
var list = clientContext.get_web().get_lists().getByTitle(listName);
var item = list.getItemById(id);
clientContext.load(item);
clientContext.executeQueryAsync(Function.createDelegate(this,function(){
// get current field value...
var currentValue = item.get_item(fieldName);
item.set_item(fieldName, newValue + currentValue);
item.update();
// update the field with the new value
clientContext.executeQueryAsync();
}),Function.createDelegate(this,function(sender,args){alert(args.get_message());}));
}
Note that when using the JavaScript Client Object Model, you need to wait for the SP.JS library to load first. This can be accomplished using the built-in ExecuteOrDelayUntilScriptLoaded method like so:
ExecuteOrDelayUntilScriptLoaded(yourFunctionName,"SP.JS");
or
ExecuteOrDelayUntilScriptLoaded(function(){
// your code here
},"SP.JS");

Binding dropdown list using ajax and jQuery

I would like to bind the data from splunk to a dropdown list.
The servlet return a JsonString by gson
Gson gson = new Gson();
String jsonString = gson.toJson(arrays);
resp.getWriter().write(jsonString);
In the jsp, ajax was used to get back the jsonString and blind in drop down list.
$(document).ready(function() {
$.ajax({
type: "POST",
dataType : "json",
url : "../getName",
success : function(data) {
console.log("success to return name");
if (msg) {
alert("Somebody" + name + " was added in list !");
location.reload(true);
} else {
alert("Cannot add to list !");
}
$.each(objdata["wlsDomain"], function(i, val) {
jQuery('#DropdownList').append('<option value="' + val.name + '</option>');
});
};
)};
)];
It said $(...).ready is not a function. If I change the "$" to "jQuery", then there is no warning. However, binding is failed.
Then I have also tried the below code for knowing whether the ajax is workable.
And it showed "Fail". Therefore, the ajax is not workable.
jQuery(document).ready(function() {
var promise =jQuery.ajax({
type: "POST",
url: "../getName",
dataType: "json"
});
promise.fail( function() {
window.alert("Fail!");
});
promise.done( function() {
window.alert("Success!");
});
May I know what's wrong with this?
And how can I bind the name get from splunk to a dropdown list?
Thanks!

Try the following code:
$(document).ready(function () {
var $el = $('#DropdownList');
var url = "../getName";
$.getJSON(url, {}, function (data) {
$el.empty(); // remove old options
$.each(data, function(index, obj) {
$el.append($("<option></option>")
.attr("value", obj.name).text(obj.name));
});
} );
});
