how to check URL is correct or not when i will enter into dynamically added textbox .
here t3 is given as id of input tag but that is works only for first dynamically added textbox not for others.
how to validate another URL present into next dynamically added textbox ?
<script type="text/javascript">
function GetDynamicTextBox(value){
return '<Label> Enter the URL : </label>' +
'<input name = "habits" type="text" id = "t3" value = "' + value + '" />' +
' <input type="button" value="Remove" onclick = "RemoveTextBox(this)" /><br><br>'
}
function AddTextBox() {
var div = document.createElement('DIV');
div.innerHTML = GetDynamicTextBox("");
document.getElementById("TextBoxContainer").appendChild(div);
}
function RemoveTextBox(div) {
document.getElementById("TextBoxContainer").removeChild(div.parentNode);
}
function RecreateDynamicTextboxes() {
var values = eval('<%=Values%>');
if (values != null) {
var html = "";
for (var i = 0; i < values.length; i++) {
html += "<div>" + GetDynamicTextBox(values[i]) + "</div>";
}
document.getElementById("TextBoxContainer").innerHTML = html;

I think you can first try to add an "onchange" handler to the "TextBoxContainer" div and user event.target or event.srcElement to identify whether it is a textbox that triggered the "onchange" event. If the trigger dom is exactly the ones you want, then you can try to validate its value and if it is not, you don't need to do anything. If this is done, then the rest things will be simply add/remove textboxes to the container element. Below are some sample codes that may help:
<script type="text/javascript">
var _container = document.getElementById('TextBoxContainer');
function add(){
var _txt = document.createElement("INPUT");
_txt.type = "text";
_container.appendChild(_txt);
}
_container.onchange = function(event){
var _dom = event.target || event.srcElement;
if(_dom && _dom.tagName === "INPUT" && _dom.type === "text"){
//alert(_dom.value);
//You can validate the dom value here
}
};
document.getElementById('add').onclick=function(){
add();
};
</script>

I have written the code of taking input value from a text box and adding it to an array using the add button and also displaying the values of the array when the display button is clicked.
The thing is I did all this using JavaScript and now I want to do it using jQuery. I tried a code snippet from this website but it's not working. Please help.
<body>
<script src="jquery-3.3.1.js"></script>
<input type="text" id="text1"></input>
<input type="button" id="button1" value="Add" onclick="add_element_to_array();"></input>
<input type="button" id="button2" value="Display" onclick="display_array();"></input>
<div id="Result"></div>
<script>
var x = 0;
var sample = []; // <-- Define sample variable here
function add_element_to_array(){
$(document).on('click', '#btnSubmit', function () {
var test = $("input[name*='i_name']");
$(test).each(function (i, item) {
sample.push($(item).val());
});
console.log(sample.join(", "));
});
}
function display_array() {
var e = "<hr/>";
for (var y = 0; y < sample.length; y++) {
e += "Element " + y + " = " + sample[y] + "<br/>";
}
document.getElementById("Result").innerHTML = e;
}
</script>
</body>
You can use this code to get idea of how it should work. You can also check for non-empty value before pushing the value into the array as an empty value in array will not make any sense.
$(document).ready(function(){
var valueArray = [];
//add value in array
$('#button1').click(function(){
var textValue = $('#text1').val();
//push non empty value only
if(textValue.trim() !== ''){
valueArray.push(textValue);
//reset the text value
$('#text1').val('');
}
});
//display value
$('#button2').click(function(){
$('#Result').html(valueArray.toString());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="text1"></input>
<input type="button" id="button1" value="Add"></input>
<input type="button" id="button2" value="Display"></input>
<div id="Result"></div>
I have added the jquery script considering the following as your suggested html.
<input type="text" id="text1"></input>
<input type="button" id="button1" value="Add"></input>
<input type="button" id="button2" value="Display"></input>
<div id="Result"></div>
The inptArr must be a global array.
<script>
var inptArr = [];
$('#button1').on('click',function(){
if($('#text1').val() != '')
inptArr.push($('#text1').val());
});
$('#button2').on('click',function(){
var string = '';
var lastIndex = parseInt(inptArr.length - 1);
for(var i = 0; i <= lastIndex ; i++)
{
if(i == lastIndex)
string += inptArr[i];
else
string += inptArr[i] + ',';
}
$('#Result').append(string);
});
</script>
This is another way to achieve what you want with minor changes.
You have only one text input element so don't need any each loop.
document.ready() is needed if you define script from starting of the code because at starting there is no defined element that have an id as btnSubmit so this block must wait to dom elements to be ready.
Also you don't need pure javascript code getElementById on display_array() function when you use jquery. You can change it as $("#Result").html(e);
var x = 0;
var array = [];
$(document).ready(function(){
$('#btnSubmit').on('click', function () {
array.push($("#text1").val());
});
});
function display_array() {
var e = "<hr/>";
for (var y = 0; y < array.length; y++) {
e += "Element " + y + " = " + array[y] + "<br/>";
}
$("#Result").html(e);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="text1"/>
<input type="button" id="btnSubmit" value="Add"/>
<input type="button" id="button2" value="Display" onclick="display_array();"/>
<div id="Result"></div>
In your code functions passed to onclick attributes are binding the click event to a DOM - don't do that.
var array = Array();
var input = $("#text1");
var result = $("#result");
function add_element_to_array(){
var value = input.val();
array.push(value);
console.log("Add:", value);
// input.val(""); // bonus: clears input after adding text to an array
}
function display_array() {
result.text(array.toString());
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="text1">
<input type="button" id="button1" value="Add" onclick="add_element_to_array();">
<input type="button" id="button2" value="Display" onclick="display_array();">
<div id="result"></div>
I want to insert a value into <input type="text" id="getdobtval"> when I am selecting a range value.
For showing output in browser am using <span id="getdobtval"></span> instead of this span I want insert into text. How can I solve this using javascript?
jQuery(document).ready(function() {
$('#slider-bottom').slider().on('slide', function(ev) {
var finalvalue = '';
var finalbtvalue = '';
var finalbtprice = '';
var finalbitvalue = '';
finalbtprice = 250;
var newVal = $('#slider-bottom').data('slider').getValue();
var textval = parseInt(newVal);
if (textval >= 600 && textval < 6000) {
finalvalue = 0.075;
finalbitvalue = textval * finalvalue;
} else if (textval >= 6000 && textval < 30000) {
finalvalue = 0.070;
finalbitvalue = textval * finalvalue;
} else if (textval >= 30000) {
finalvalue = 0.065;
finalbitvalue = textval * finalvalue;
}
finalbtvalue = finalbitvalue / finalbtprice;
if (finalbtvalue) {
$("#getdobtval").html("<strong>" + finalbtvalue.toFixed(8) + "</strong>");
}
});
$('#slider-bottom').sliderTextInput();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" method="post">
<input id="slider-bottom" type="text" name="hrate" data-slider-min="600" data-slider-max="100000" data-slider-step="1" data-slider-value="600" data-slider-tooltip="show" />
<span id="getdobtval"></span>
<input type="text" id="getdobtval" name="getdobtval">
<input type="submit" name="buynow">
</form>
Create a hidden input box with different id like dobtval
<form action="" method="post">
<input id="slider-bottom" type="text" name="hrate" data-slider-min="600" data-slider-max="100000" data-slider-step="1" data-slider-value="600" data-slider-tooltip="show" />
<span id="getdobtval"></span>
<input type="hidden" id="dobtval" name="dobtval"/>
<input type="submit" name="buynow">
</form>
And in JS use,
....
if (finalbtvalue) {
$('#dobtval').val(finalbtvalue.toFixed(8));// set value in input
$("#getdobtval").html("<strong>" + finalbtvalue.toFixed(8) + "</strong>");
}
....
id must be unique, but if you want same HTML then differentiate your elements by their tag name like,
$('span#getdobtval').html('....'); // use html() span/div
$('input#getdobtval').val('....'); // use val() for input/textarea

First, this is my first time learning JS.
So, I have a text-box, a submit button, and a display button. When I enter a number in the text-box, and click submit, it shows the number. I enter my second number and clicking the submit button shows me the second number. Then I click on the display button, it will shows the number 1 and number 2 in order. If I have more inputs in the text-box, the display button will show the entire list of all the inputs from the array.
Thank you!
Well, since it's your first time and you're learning I won't just give you the answer, but I'll point you in the right direction.
You want to attach a click event on the submit button to add the value to an array, and then print the array on click of the display button.
i think first you must google for this. I write something and you can improve this. I only want to give an example.
HTML:
<input type="text" id="inputbox">
<br/>
<button type="button" id="submit">Submit</button>
<button type="button" id="display">Display</button>
<br/>
<div id="screen"></div>
JS:
var inputArray = [];
var input = document.getElementById('inputbox');
var screen = document.getElementById('screen');
document.getElementById('submit').onclick = function () {
inputArray.push(input.value);
screen.innerHTML = input.value;
};
document.getElementById('display').onclick = function () {
screen.innerHTML = inputArray
};

Change add button's type "submit" to "button" then remove return statement from add function as it is not needed.
This code has many issues.
You don't need four array to store address detail. you can make one array that can have objects containing the address information.eg.
var Address=function(name,address,email,mobile){
this.name=name;
this.address=address||"not available";
this.email=email||"not available";
this.mobile=mobile;
}
var AddressBook=new Array();
//Adding data in address book
AddressBook.push(new Address("jhon","baker street","a#in.com","049372497"))
You can use jquery to get value of element instead of pure javascript. eg.
var conname = document.getElementById('userNam').value;
//instead of this use jquery
var conname=$("#userNam").val(); // recommended approach
There is no need to calculate array length everywhere.To check duplicate mobile number you can write a function.
there are many other improvement you can have in code. for more examples go through Jquery site and Github public repositories.
Fiddle Demo
Change the <input id="add" type="submit" value="AddToContacts" /> to type="button". type="submit" will refresh the page to form's action and will reset all variables including BOOK.
I have an issue to create dynamic fields with string count using JavaScript or jQuery.
Briefing
I want to create dynamic fields with the help of sting count, for example when I write some text on player textfield like this p1,p2,p3 they create three file fields on dynamicDiv or when I remove some text on player textfield like this p1,p2 in same time they create only two file fields that's all.
The whole scenario depend on keyup event
Code:
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
function commasperatedCount(){
var cs_count = $('#player').val();
var fields = cs_count.split(/,/);
var fieldsCount = fields.length;
for(var i=1;i<=fieldsCount;i++){
var element = document.createElement("input");
element.setAttribute("type", 'file');
element.setAttribute("value", '');
element.setAttribute("name", 'file_'+i);
var foo = document.getElementById("dynamicDiv");
foo.appendChild(element);
}
}
</script>
<form>
<label>CountPlayerData</label>
<input type="text" name="player" id="player" onkeyup="return commasperatedCount();" autocomplete="off" />
<div id="dynamicDiv"></div>
<input type="submit" />
</form>
var seed = false,
c = 0,
deleted = false;
$('#player').on('keyup', function(e) {
var val = this.value;
if ($.trim(this.value)) {
if (e.which == 188) {
seed = false;
}
if (e.which == 8 || e.which == 46) {
var commaCount = val.split(/,/g).length - 1;
if (commaCount < c - 1) {
deleted = true;
}
}
commasperatedCount();
} else {
c = 0;
deleted = false;
seed = false;
$('#dynamicDiv').empty();
}
});
function commasperatedCount() {
if (deleted) {
$('#dynamicDiv input:last').remove();
deleted = false;
c--;
return false;
}
if (!seed) {
c++;
var fields = '<input value="" type="file" name="file_' + c + '">';
$('#dynamicDiv').append(fields);
seed = true;
}
}
