How can I add validation to an Input field? Binding JSON model doesn't work

I try to learn SAPUI5 with Samples frpm Demo kit Input - Checked. I get an error message: oInput.getBinding is not a function
I have a simple input field xml:
<Label text="Name" required="false" width="60%" visible="true"/>
<Input id="nameInput" type="Text" enabled="true" visible="true" valueHelpOnly="false" required="true" width="60%" valueStateText="Name must not be empty." maxLength="0" value="{previewModel>/name}" change= "onChange"/>
and my controller:
_validateInput: function(oInput) {
var oView = this.getView().byId("nameInput");
oView.setModel(this.getView().getModel("previewModel"));
var oBinding = oInput.getBinding("value");
var sValueState = "None";
var bValidationError = false;
try {
oBinding.getType().validateValue(oInput.getValue());
} catch (oException) {
sValueState = "Error";
bValidationError = true;
}
oInput.setValueState(sValueState);
return bValidationError;
},
/**
* Event handler for the continue button
*/
onContinue : function () {
// collect input controls
var that = this;
var oView = this.getView();
var aInputs =oView.byId("nameInput");
var bValidationError = false;
// check that inputs are not empty
// this does not happen during data binding as this is only triggered by changes
jQuery.each(aInputs, function (i, oInput) {
bValidationError = that._validateInput(oInput) || bValidationError;
});
// output result
if (!bValidationError) {
MessageToast.show("The input is validated. You could now continue to the next screen");
} else {
MessageBox.alert("A validation error has occured. Complete your input first");
}
},
// onChange update valueState of input
onChange: function(oEvent) {
var oInput = oEvent.getSource();
this._validateInput(oInput);
},
Can someone explain to me how I can set the Model?

Your model is fine and correctly binded.
The problem in your code is here, in the onContinue function
jQuery.each(aInputs, function (i, oInput) {
bValidationError = that._validateInput(oInput) || bValidationError;
});
aInput is not an array, so your code is not iterating on an array element.
To quickly fix this, you can put parentheses around the declaration like this:
var aInputs = [
oView.byId("nameInput")
];
Also, you could remove the first two lines of the _validateInput method since they are useless...

Usually, we set the model once the view is loaded, not when the value is changed. For example, if you would like to set a JSONModel with the name "previewModel", you can do as mentioned below.
Note that onInit is called when the controller is initialized. If you bind the model properly as follows, then the oEvent.getSource().getBinding("value") will return the expected value.
onInit: function(){
var oView = this.getView().byId("nameInput");
oView.setModel(new sap.ui.model.json.JSONModel({
name : "HELLO"
}), "previewModel");
},
onChange: function(oEvent) {
var oInput = oEvent.getSource();
this._validateInput(oInput);
},
...
Also, for validating the input text, you can do the following:
_validateInput: function(oInput) {
var oBinding = oInput.getBinding("value");
var sValueState = "None";
var sValueStateText = "";
var bValidationError = false;
if(oBinding.getValue().length === 0){
sValueState = "Error";
sValueStateText = "Custom Error"
}
oInput.setValueState(sValueState);
if(sValueState === "Error"){
oInput.setValueStateText(sValueStateText);
}
return bValidationError;
},
Please note that the code above is not high quality and production ready as it's a quick response to this post :)

How to change a field type in netsuite?

I am trying to create an online form using Netsuite.
We have a set for predefined fields like firstname, lastname, etc.
In the same we have a
NLSUBSCRIPTIONS
tag but the field type by default is drop down with multiple select option.
How can I change this drop down to a checkbox?

If you use a custom template you can hide the drop-down and iterate its options to create your own checkboxes.
e.g.
<div class="regFieldWrap">
<span class='cbExpand hideNsLabel'><NLCUSTENTITY_LIST_FIELD></span><input class="otherShadow valid" type="text" name="custentity_list_field_other"><span class="multiProto cbHolder"><input type="radio" name="custentity_list_field"><label class="cbLabel"></label></span>
</div>
and then
<script>
jQuery(function($){
// convert multi select to checkbox
$("span.multiProto").each(function(){
var proto = this;
var selName = $(proto).find("input").attr("name");
var otherCB = null;
$("select[name='"+selName+"']").css({display:'none'}).each(function(){
var sel = $(this);
var isReq = sel.hasClass('inputreq');
if(isReq) sel.removeClass('inputreq');
sel.find("option").each(function(){
if(!this.value) return;
var newby = $(proto.cloneNode(true));
var cb = newby.find("input").val(this.value);
if(isReq) cb.addClass('cb_selectone');
newby.find("label.cbLabel").text(this.text);
$(newby).removeClass('multiProto');
if((/\bother\b/i).test(this.text)){
var otherField = $("input.otherShadow[name='"+ selName+"_other']").each(function(){
var newOther = this.cloneNode(true); // strange but it gets around an IE issue
$(this).remove();
$(newby).find("input").data("conditionalOther", newOther);
newby.get(0).appendChild(newOther);
});
otherCB = newby;
} else proto.parentNode.insertBefore(newby.get(0), proto);
});
sel.get(0).options.length = 0;
});
if(otherCB) proto.parentNode.insertBefore(otherCB.get(0), proto); // make sure this is the end element
});
});

Using javascript Not able to disable textbox.It Immediatly enable after disabled. Can anyone give me solution?

I have One simple registration Form which is developed in C#.Net. This form also contain one Grid view which display data from database.In this,I want to disable Insert button when i select particular raw data. and i had develop this code in jquery. I used below code.
function DoStuff(lnk) {
debugger;
var grid = document.getElementById('GridView1');
var cell, row, rowIndex, cellIndex;
cell = lnk.parentNode;
row = cell.parentNode;
rowIndex = row.rowIndex;
cellIndex = cell.cellIndex;
var rowId = grid.rows[rowIndex].cells[0].textContent;
var rowname = grid.rows[rowIndex].cells[1].textContent;
var rowcontact = grid.rows[rowIndex].cells[2].innerHTML;
var rowaddress = grid.rows[rowIndex].cells[3].innerHTML;
var rowemail = grid.rows[rowIndex].cells[4].innerHTML;
var Id = document.getElementById('txt_Id');
var name = document.getElementById('txt_Name');
var contact = document.getElementById('txt_PhoneNumber');
var address = document.getElementById('txt_Address');
var email = document.getElementById('txt_EmailId');
Id.value = rowId;
name.value = rowname;
contact.value = rowcontact;
address.value = rowaddress;
email.value = rowemail;
document.getElementById('Button1').disabled = true;
};
But when i run that page it becomes disable and immediately enable automatically.....:(
Can anyone give me solution ???

You have to call this function after form is completely loaded.
Use below code to make it that happen if you are using jQuery.
$( document ).ready(function() {
DoStuff(lnk);
});

get all checked checboxes and add their names and values in array

I have large form mainly drop down lists and checkboxes. Checkboxes are created dynamically so i don't know their id's before they are created. I use drop down onChange event to do create them on the fly.
How can i loop trough the form and get all the checkboxes that are checked, that is their id and their value? I need to do this only for check boxes that are checked. All checkboxes share the same name, that is: categoriesfilters[]. Currently i have on click event on the checkbox which invoke the javascript function.
Here is the code:
function update_number_of_adds_found(field_dropdown,selected_value) {
selected_value="";
var addtypeid = $("#addtypeid").val();
// trying to store the values of the checkboxes
$(this).find("input[type=checkbox]:checked").each(
function() {
var id = $(this).attr('id');
var value = $(this).val(); // or maybe attr('value');
// the data is stored, do whatever you want with it.
alert(value);
}
);
var selected_value = {
addtypeid: addtypeid,
// need to add the ids and the values here as well
};
var url = "<?php echo site_url('search/findNumberOfAdds'); ?>";
$.post(url, selected_value, function(r){
if(r) {
$('#totalNumOfAdds').empty();
$("#totalNumOfAdds").append(r.result);
} else {
// alert(selected_value);
}
}, 'json')
}
Regards, John

Try this :
var categories = [];
$("input[name='categoriesfilters[]']:checked").each(
function() {
var id = $(this).attr("id");
var value = $(this).val();
categories[categories.length] = {id : value};
}
);
console.log(categories);
$.post(url, categories, function(r){
...

Try this :
$('form').submit(function(){
$(this).find("input[type=checkbox]:checked").each(
function() {
var id = $(this).attr('id');
var value = $(this).val(); // or maybe attr('value');
// the data is stored, do whatever you want with it.
}
);
});
I guess you want to check that on form submit.

var arr = [];
$('input[name^="categoriesfilters"]:checked').each(function() {
var obj = {
id: $(this).attr('id');
value: $(this).val();
};
arr.push(obj);
});
console.log(arr); // show us the array of objects

Would you like to use Jquery?
Add a class to each of the checkbox i.e "class_chk";
$(function(){
$('.class_chk').each(function(){
if($(this).is(':checked')){
var id = $(this).attr('id');
var val = $(this).val();
alert("id = "+id+"---- value ="+val);
}
});
});
The above way you can get all the check box id and value those are checked.
Thanks..

add values to textbox history without submitting the form using javascript or Jquery

Hello friends I have a <input type="text" id="tempID" /> element in my form
I also have an <input type="button" onclick="doSomething()" /> element in my form.
I want to add the text box value to textbox history when user clicks on the button.
I am processing the request using Jquery ajax. So I have to do it with javascript or Jquery.
Is this possible to add values to the history of particular <input type="text" /> element using javascript/Jquery..??

Here is how you can do it using HTML5 LocalStorage
$( "#tempID" ).autocomplete({
source: function( req, resp ) {
var temp = localStorage.getItem('custom_history');
var data = JSON.parse(temp);
resp( data );
}
});
$('#tempID').on('blur', function() {
var temp = localStorage.getItem('custom_history');
var data = JSON.parse(temp);
if($.trim(this.value).length > 0)
data.push(this.value);
localStorage.setItem('custom_history', JSON.stringify(data));
});
What I am doing is Setting the value into HTML5 Local storage when users moves away from the input field, clicks somewhere else.
Then retrieving that and setting that as source for jQuery UI auto complete.
Here is a working fiddle http://jsfiddle.net/joycse06/EBduF/173/
Enter some value. Click somewhere else. Click back again and add other values. The refresh the fiddle and start typing one of those and auto complete will show up.
UPDATE
Based on his comments and later chat the final code he need is this, I am pasting in if it might someone else later
// if we dont set this line then ff will return null, and null.length will throw an error
if(!localStorage.getItem('custom_history'))
localStorage.setItem('custom_history','');
$( "#test" ).autocomplete({
source: function( req, resp ) {
var term = req.term;
var temp = localStorage.getItem('custom_history');
var data = [];
if(temp.length > 0)
data = JSON.parse(temp);
var intRegex = /^\d+$/;
data = $.map(data,function(val){
if(intRegex.test(val)){
if(val.indexOf(term) != -1)
return val;
else
return null;
}
else
return null;
});
resp( data );
}
});
$('#save').on('click', function() {
var temp = localStorage.getItem('custom_history');
var data = [];
if(temp.length > 0)
data = JSON.parse(temp);
var value = $.trim($('#test').val());
if(value.length > 0){
if($.inArray(value,data) != -1){
//alert('Duplicate');
return;
}
}
data.push(value);
localStorage.setItem('custom_history', JSON.stringify(data)); // set item to localStorage
});

You can use localStorage like following:
var arr = [];
$('input#tempID').on('click', function() {
arr.push(this.value);
localStorage.setItem('history', JSON.stringify(arr)); // set item to localStorage
});
To retrieve that value try,
var temp = localStorage.getItem('history');
if(retarr) { // checking that data it stored in localStorage or not, if not exists temp = null
var allHistories = JSON.parse(temp); // now you have history
console.log(allHistories);
}
I think you need something like autocomplete
