Data.gui.js clear text with confirm box - javascript

dat.gui.js
I am trying to use the text input in DAT.GUI.js, when I click the input box, the text input box should be clear if there has a default value. After finished, it will come out a confirm box(Message Box) to inform the user their input message.
Right now, My code is like this, but if I choose the Cancel it can not clear the input text. If the default text is not empty, I still need to delete the world use Backspace And also I do not want the default name "Close Controls", can I delete this?
var params = {
text:""
};
var gui = new dat.GUI();
gui.add(params, 'text').name('ID:').onFinishChange(function (value) {
if (confirm('Is" '+ value + ' "id?') === true) {
workerId = value;
} else {
value = "";// I also tried params.text = ""; but still can not clear the input box
}
});
Any suggestion is appreciated, thanks!
Solved
gui.add(params, 'text').name('Your Worker ID:').listen().onFinishChange(function (value) {
if (confirm('Is" '+ value + ' "your worker id?') === true) {
workerId = value;
} else {
params.text="";
}
});

gui.add(params, 'text').name('Your Worker ID:').listen().onFinishChange(function (value) {
if (confirm('Is" '+ value + ' "your worker id?') === true) {
workerId = value;
} else {
params.text="";
}
});

javascript function to prevent user from changing the value of a specific column

Hope you're doing well
I'm new to JavaScript and I need your help to complete the code below.
I've written a JS code as you can see below :
$("#input_KindCode").change(function () {
if ($(this).val() == 1) {
RunSql("Select DateKey From ProjectExecution.Contractinfo WHERE PlanCode = " + $("#input_PlanCode").val() + " AND ProjectCode = '" + $("#input_ProjectCode").val() + "' AND ContractCode = '" + $("#input_ContractCode").val() + "' AND KindCode = 1 ", function (data) {
if (data.length > 0) {
$("#input_DateKey").val(data[0].DateKey);
/////// THIS PART///////
} else {
$("#input_DateKey").val('');
EnableCol("DateKey");
}
});
}
else {
$("#input_DateKey")[0].value = '';
EnableCol("DateKey");
};});
In the 'RunSql' part of the code , I'm checking whether the 'datekey' column has value if true the value will show up in the field otherwise the user must enter the value for the column.
The problem is I want to add something to the code . I want to show the value if it exists AND I want to disable the column so that the user can not change the value . I can not use the function 'disable column' cause it does not work in my case are there any other functions ??
so I want a function to prevent user from changing the value of the column if it is being shown on the field. the function must be written in the 'This part' part of the code
Thanks in advance
You can disable this input field using jquery. To perform this you need to add one line.
Code:
if (data.length > 0) {
$("#input_DateKey").val(data[0].DateKey);
$("#input_DateKey").prop('disabled',true);
} else {
$("#input_DateKey").val('');
$("#input_DateKey").prop('disabled',false);
EnableCol("DateKey");
}

Textarea value remain the same after submitting a form

My previous problem has been fixed, now I need to ask how to keep a textarea from resetting its input after a form is submitted. Here is the jsFiddle: http://jsfiddle.net/rz4pnumy/
Should I change the form in the HTML?
<form id="form1" method="GET">
(the form does not go into a php file or anything else, i'm using it to submit the textarea input and use the variables I made using jQuery to make a paragraph on the same page)
or something in the JS?
$(document).ready( function () {
$('#form1').on('submit', function (event) {
// If the form validation returns false, block the form from submitting by
// preventing the event's default behaviour from executing.
if (!validate()) {
event.preventDefault();
}
if(validate()) {
var adjective1 = $('#adjective1').val();
var adjective2 = $('#adjective2').val();
var pluralnoun = $('#plural-noun').val();
var verb1 = $('#verb1').val();
var edibleobject = $('#edible-object').val();
var monster1 = $('#monster1').val();
var adjective3 = $('#adjective3').val();
var monster2 = $('#monster2').val();
var verb2 = $('#verb2').val();
$('body').append(
'<div id="para">' +
'<p>Rain was still lashing the windows, which were now ' + adjective1 +', but inside all looked bright and cheerful. ' +
'The firelight glowed over the countless ' + adjective2 + '' + pluralnoun + ' where people sat ' + verb1 + ', talking, ' +
'doing homework or, in the case of Fred and George Weasley, trying to find out what would happen if you fed a ' + edibleobject +' to a ' + monster1 + '.' +
'Fred had "rescued" the ' + adjective3 + ', fire-dwelling ' + monster2 + ' from a Care of Magical Creatures class and it was now ' + verb2 + ' gently ' +
'on a table surrounded by a knot of curious people. </p>' +
'</div>'
);
}
});
function validate() {
var success = true;
$('.input').each(function(i, item) {
if ($(item).val() === "")
{
console.log("Missing textarea input");
success = false;
$(item).attr("style","border:1px solid red;");
//note it will overwrite your element style in all Input class
}
else
{
$(item).removeAttr('style')
// to remove border
}
});
return success;
}
});
The contents get emptied after pressing submit and I only see the completed paragraph for a split second.
You need to prevent the default event handler from executing whether validate passes or not, so you need to remove the if statement around the event.preventDefault() call. The preventDefault is the function that is keeping the from from submitting and re-loading your page.
Also, your Fiddle was not set to jQuery (it was set to no-library) so that may have also been causing you issues during your testing.
Edited for example of what I'm talking about:
$('#form1').on('submit', function (event) {
// block the form from submitting by
// preventing the event's default behaviour from executing.
event.preventDefault();
if(validate()) {
var adjective1 = $('#adjective1').val();
var adjective2 = $('#adjective2').val();
var pluralnoun = $('#plural-noun').val();
... etc ...
I would use php and set a variable to the GET value of the textarea and set the value of the textarea to that variable

reset values of not selected fields of dropdown

I have a dropbox that when selected it displays its respective fields
in first image you can see there is A person without an ID so when selected it displays
something like:
if you see I added 12
Now if i change my mind and select the other option (person with ID) one field is displayed like:
I added 9999
That is ok, but now if I change my mind again and return to other selected option the values are still there like:
I would like to clean them... How can I accomplish that?
It does not matter to fill all respective fields again, I want to reset values in that case if select
person without ID, delete the 9999, on the other hand, if i select person with Id, i want to reset the vakue 12
please take a look at my fiddle
some of the jquery code is:
//function available
function validate(id, msg) {
var obj = $('#' + id);
if(obj.val() == '0' || obj.val() == ''){
$("#" + id + "_field_box .form-error").html(msg)
return true;
}
return false;
}
$(function () {
$('#has_id').show();
$('#select_person').change(function () {
$('.persons').hide();
if ($('#select_person').val() == 'typeA') {
$("#has_id").html('');
$("<option/>").val('0').text('--Choose Type A--').appendTo("#has_id");
$("<option/>").val('person-A-withID').text('person-A-withID').appendTo("#has_id");
$("<option/>").val('person-A-withoutID').text('person-A-withoutID').appendTo("#has_id");
}
if ($('#select_person').val() == 'typeB') {
$("#has_id").html('');
$("<option/>").val('0').text('--Choose Type B--').appendTo("#has_id");
$("<option/>").val('person-B-withID').text('person-B-withID').appendTo("#has_id");
$("<option/>").val('person-B-withoutID').text('person-B-withoutID').appendTo("#has_id");
}
});
$('#has_id').change(function () {
$('.persons').hide();
$('#' + $(this).val()).show();
});
});
var validation = function(){
var err = 0;
err += validate('select_person', "select person.");
err += validate('has_id', "Select whether it has an ID or not.");
if(err == 0){
alert('continue');
}else{
alert('error');
}
};
Simply make this change:
$('#has_id').change(function () {
$('.persons input').val('');
$('.persons').hide();
$('#' + $(this).val()).show();
});
New fiddle: http://jsfiddle.net/6m27M/
This simply clears out all the values any time a change is made to the #has_id dropdown.

JavaScript back button to display previous list

I want create a web application that display a list of items. Suppose I have displayed a list view (say listobject1) of 3 items. when clicked on any of them I get new list view (say listobject2) which its value is according to listobject1. When again I click one of them I get another view. Now when I click back button i want to go back to previous list view i.e. when I'm now on listobject2 and again when back button is pressed I want to show listobject1. Can anybody tell me how I can do this in JavaScript?
Edit
I'm still study about the stuff but I can't solve this problem yet. In order to clarify my problem now, here's my code:
$(document).ready(function() {
$("#result").hide();
$("input[name='indexsearch']").live("click", function() {
$("#result").show();
$("#result").empty();
loading_img();
var $textInput = $("[name='valueLiteral']").val();
$.getJSON("get_onto", {
"input" : $textInput
}, function(json) {
if(json.length > 0 ) {
var arrayPredicate = [];
var arrayObject = [];
var arraySubject = [];
$.each(json, function(index, value) {
arraySubject[index] = value.subject;
arrayPredicate[index] = value.predicate;
if(value.objectGeneral != null) {
arrayObject[index] = value.objectGeneral;
} else {
arrayObject[index] = value.objectLiteral;
}
}
);
var stmt = [];
//concat all related array into string (create triple statement)
$.each(arrayPredicate, function(k,v){
stmt[k] = "<span class='subject' id="+arraySubject[k]+">"
+ arraySubject[k] + "</span> " + " -> " + v + " : "+
//change object from text to be button form
"<button class = 'searchAgain-button' name = 'searchMore' \n\
value = " + arrayObject[k] + ">" + arrayObject[k] + "</button><br> <br>";
});
stmt = stmt.sort();
$.each(stmt, function(k,v){
$("#result").append(v);
});
} else {
var $noresult = "No Result : Please enter a query";
$("#result").append($noresult);
}
});
});
$("button").live("click", function() {
$("#result").show();
$("#result").empty();
loading_img();
var $textInput = $(this).attr("Value");
//var $textInput = "G53SQM";
$.getJSON("get_onto", {
"input" : $textInput
}, function(json) {
if(json.length > 0 ) {
var arrayPredicate = [];
var arrayObject = [];
var arraySubject = [];
$.each(json, function(index, value) {
arraySubject[index] = value.subject;
arrayPredicate[index] = value.predicate;
if(value.objectGeneral != null) {
arrayObject[index] = value.objectGeneral;
} else {
arrayObject[index] = value.objectLiteral;
}
}
);
var stmt = [];
var searchMore = "searchMore";
//concat all related array into string (create triple statement)
$.each(arrayPredicate, function(k,v){
stmt[k] = "<span class='subject' id="+arraySubject[k]+">" + arraySubject[k] + "</span> " + " -> " + v + " : "+ " <button class = 'searchAgain-button' name = " +searchMore + " value = " + arrayObject[k] + ">" + arrayObject[k] + "</button><br><br>";
});
stmt = stmt.sort();
$.each(stmt, function(k,v){
$("#result").append(v);
});
} else {
var $noresult = "No Result : Please enter a query";
$("#result").append($noresult);
}
});
});
At first, user only see one button name "valueLiteral". After user perform 1st search, the result is return in a form of JSON and eventually put in stmt[] to display, which at this state the second button was create as a clickable-result which will automatically take the value of result and do second search if user click the second button.
Now the problem is, I want to add a 3rd HTML button name "back" to make the web display the previous result in stmt[] if user click on the button.
Hope this helps in clarify the problems, I'm still doing a hard work on this stuff since I'm a newbie in JavaScript. Appreciate all helps.
This is what you want almost exactly the way you want it.
You'll have to use history.pushState to push these fake events into the history.
Alternatively, you can use location.hash to store the current object, and update the hash every time you display a new list. Then onhashchange find the hash and display the appropriate list.
See http://jsfiddle.net/cFwME/
var history=[new Array(),new Array()];
history[0].id="#back";
history[1].id="#next";
Array.prototype.last=function(){
return this[this.length-1];
}
$('#list>li:not(:first)').click(function(){
if(!history[0].length || history[0].last().html()!=$('#list').html()){
history[0].push($('#list').clone(true,true));
$(history[0].id).prop('disabled',false);
history[1].length=0;
$(history[1].id).prop('disabled',true);
}
$('#list>li:first').html('This is List '+$(this).index());
});
$('#back').click(getHistory(0));
$('#next').click(getHistory(1));
function getHistory(n){
return function(){
if(!history[n].length){return false;}
history[(n+1)%2].push($('#list').replaceWith(history[n].last()));
history[n].pop();
$(history[(n+1)%2].id).prop('disabled',false);
if(!history[n].length){$(history[n].id).prop('disabled',true);}
}
}

Javascript form validation with Jquery decoration

Please excuse my lack of javascript seasoning. I currently have two parts to my validation:
1. functions that apply css decoration to the input fields and makes the div that contains the error message visible
2. a function that aggregates the above functions and is called in the form ie, onSubmit="(return validate();)"
I wish to fix two things:
1. Refactor code so as to make it smaller
2. FIXED with code update. Apply selector text decoration to all empty fields. Currently, the decoration is applied to the first empty field then once a text value is entered, it hits the next field. Every empty field should be validated and show proper decoration.
/** VALIDATION DECORATION **/
function validateAccountNameRequired(textInputId, textInputLabelName) {
var valid = true;
if (!$('input#accountName').val()) {
$('input#accountName').addClass('inputError');
$('ul#accountNameList').find('div.error').attr('style', '');
valid = false;
} else if ($('input#accountName').val()) {
$('input#accountName').removeClass('inputError');
$('ul#accountNameList').find('div.error').hide();
}
return valid;
}
function validateAccountBusOrgIDRequired(textInputId, textInputLabelName) {
var valid = true;
if (!$('input#accountBusOrgID').val()) {
$('input#accountBusOrgID').addClass('inputError');
$('ul#busOrgList').find('div.error').attr('style', '');
valid = false;
} else if ($('input#accountBusOrgID').val()) {
$('input#accountBusOrgID').removeClass('inputError');
$('ul#busOrgList').find('div.error').hide();
}
return valid;
} /** VALIDATORS **/
function validate() {
valid = validateAccountNameRequired('accountName', 'Account Name');
valid1 = validateAccountBusOrgIDRequired('accountBusOrgID', 'Account Bus Org ID');
return valid && valid1;
}
I resolved my own issue. Hopefully someone else can benefit:
Validates all fields at once
Refactored for better cohesion, just load values in function validate() and reuse one function validateTextRequired():
function validateTextRequired( textInputId, errorListId)
{
var valid = true;
if( !$('input' + '#' + textInputId).val())
{
$('ul' + '#' + errorListId).find('label').addClass('error');
$('input' + '#' + textInputId).addClass('inputError');
$('ul' + '#' + errorListId).find('div.error').attr('style','');
valid = false;
} else if ($('input#' + textInputId).val()) {
$('ul' + '#' + errorListId).find('label').removeClass('error');
$('input' + '#' + textInputId).removeClass('inputError');
$('u' + 'l#' + errorListId).find('div.error').hide();
}
return valid;
}
function validate()
{
valid = validateTextRequired( 'accountName', 'accountNameList');
valid1 = validateTextRequired( 'accountBusOrgID', 'busOrgList');
valid2 = validateTextRequired( 'acctMgr', 'accountMgrList');
}
