How can I do this through the tag itself?
Change type from text to password
<input type='text' name='pass' />
Is it possible to insert JavaScript code inside the input tag itself to change type='text' to type='password'?
Try:
<input id="hybrid" type="text" name="password" />
<script type="text/javascript">
document.getElementById('hybrid').type = 'password';
</script>
Changing the type of an <input type=password> throws a security error in some browsers (old IE and Firefox versions).
You’ll need to create a new input element, set its type to the one you want, and clone all other properties from the existing one.
I do this in my jQuery placeholder plugin: https://github.com/mathiasbynens/jquery-placeholder/blob/master/jquery.placeholder.js#L80-84
To work in Internet Explorer:
dynamically create a new element
copy the properties of the old element into the new element
set the type of the new element to the new type
replace the old element with the new element
The function below accomplishes the above tasks for you:
<script>
function changeInputType(oldObject, oType) {
var newObject = document.createElement('input');
newObject.type = oType;
if(oldObject.size) newObject.size = oldObject.size;
if(oldObject.value) newObject.value = oldObject.value;
if(oldObject.name) newObject.name = oldObject.name;
if(oldObject.id) newObject.id = oldObject.id;
if(oldObject.className) newObject.className = oldObject.className;
oldObject.parentNode.replaceChild(newObject,oldObject);
return newObject;
}
</script>
Yes, you can even change it by triggering an event
<input type='text' name='pass' onclick="(this.type='password')" />
<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">
Here is what I have for mine.
Essentially you are utilizing the onfocus and onblur commands in the <input> tag to trigger the appropriate JavaScript code. It could be as simple as:
<span><input name="login_text_password" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="this.select(); this.setAttribute('type','text');" /></span>
An evolved version of this basic functionality checks for and empty string and returns the password input back to the original "Password" in the event of a null textbox:
<script type="text/javascript">
function password_set_attribute() {
if (document.getElementsByName("login_text_password")[0].value.replace(/\s+/g, ' ') == "" ||
document.getElementsByName[0].value == null) {
document.getElementsByName("login_text_password")[0].setAttribute('type','text')
document.getElementsByName("login_text_password")[0].value = 'Password';
}
else {
document.getElementsByName("login_text_password")[0].setAttribute('type','password')
}
}
</script>
Where HTML looks like:
<span><input name="login_text_password" class="roundCorners" type="text" value="Password" onfocus="this.select(); this.setAttribute('type','password');" onblur="password_set_attribute();" /></span>
let btn = document.querySelector('#btn');
let input = document.querySelector('#username');
btn.addEventListener('click',()=> {
if ( input.type === "password") {
input.type = "text"
} else {
input.type = "password"
}
})
<input type="password" id="username" >
<button id="btn">change Attr</button>
I had to add a '.value' to the end of Evert's code to get it working.
Also I combined it with a browser check so that the input type="number" field is changed to type="text" in Chrome since 'formnovalidate' doesn't seem to work right now.
if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1)
document.getElementById("input_id").attributes["type"].value = "text";
This is a simple toggle with jQuery. It works also with the the ASP.NET MVC EditorFor() when you have a DataType.Password on the model property.
function showPassword() {
let password = $(".password");
if (password[0].type == "password") {
password[0].type = "";
}
else {
password[0].type = "password";
}
}
$(".show-pass").click(function (e) {
e.preventDefault();
var type = $("#signupform-password").attr('type');
switch (type) {
case 'password':
{
$("#signupform-password").attr('type', 'text');
return;
}
case 'text':
{
$("#signupform-password").attr('type', 'password');
return;
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="password" class="show-pass">
This is not supported by some browsers (Internet Explorer if I recall), but it works in the rest:
document.getElementById("password-field").attributes["type"] = "password";
or
document.getElementById("password-field").attributes["type"] = "text";
You can try this:
const myTimeout = setTimeout(show, 5000);
function show() {
document.getElementById('pass').type = "text";
}
clearTimeout(myTimeout);
//html
<input type="password" id="password_input">
<i onclick="passwordDisplay()" class="ti-eye"></i>
//js
const input = document.getElementById("password_input")
function passwordDisplay() {
if (input.attributes["type"].value == "text")
input.attributes["type"].value = "password"
else
input.attributes["type"].value = "text"
}

note : to understand, first it shows the existing value, then in the button click , assign your new value , then display.(display with alsert, because then you can understand easily)
to assign the values in button click

do above in button click. hope this will help.
to get 10000 as the new value, in your button click

I'm trying to clear a text field and it does not work. I get the alert but it does not clear it. What am I doing wrong?
This is a generic function that can be call on any text field.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function clearThis(target)
{
alert('before...' + target.value);
if ($(target).value == "Search ")
{
$(target).value = "set to something else";
$(target).style.color = '#000000';
$(target).style.fontStyle = 'italic';
}
else
{
$(target).value = "";
}
alert('after...' + target.value);

Your use of $ would suggest that you are using JQuery but you arent including the library in your page.
If you are using jQuery, use the correct jQuery way to get and set values (.val()) and styles(.css()). And of course, include the jQuery library...
function clearThis(target) {
alert('before...' + target.value);
if ($(target).val() == "Search ") {
$(target).val('set to something else');
$(target).css({'color':'#000000', 'font-style': 'italic'})
} else {
$(target).val('');
}
alert('after...' + target.value);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="historysearch">
<input id="username" type="text" value="Search " onclick="clearThis(this)" />
</div>
If, in fact, you aren't using jQuery, you need to omit the $() syntax from your code..
function clearThis(target) {
alert('before...' + target.value);
if (target.value == "Search ") {
target.value = "set to something else";
target.style.color = '#000000';
target.style.fontStyle = 'italic';
} else {
target.value = "";
}
alert('after...' + target.value);
}
<div class="historysearch">
<input id="username" type="text" value="Search " onclick="clearThis(this)" />
</div>
Please check below code
function clearThis(target)
{
// alert('before...' + target.value);
//alert(target);
if (target.value == "Search ")
{
target.value = "set to something else";
target.style.color = '#000000';
target.style.fontStyle = 'italic';
}
else
{
target.value = "";
}
//alert('after...' + target.value);
}
HTML code
<div class="historysearch">
<input id="username" type="text" value="Search " onclick="clearThis(this)"/>
</div>
Two thing you need to update in your code first one is you should add jquery.js file and second one is if you want change value go through id or class.

You are doing it wrong.
$(target) is jquery object and not js so value could not be accessible
You can do like this(js) :
target.value
or
Like this (jquery)
$(target).val()
To Clear the textbox value using JQuery, Use following Line:
$(control).val("");
hi guys i am new to js and html.I need a o/p as when click the button tat should show the all contents entered in form...
My code for giving alert of all entered data in single
how can I add values of form textbox using string ,for loop all should be only in javascript...or else give your own code with the conditions i said....

Try that for a start

// if you want the element with the name ABC use getElementsByName()

you have just minor mistake that is you used str in place of str1; Now use the above code.
Try something like:
function processFormData() {
var inputs = document.getElementsByTagName("input"),
i,
len,
stringBuffer = [],
str;
for (i = 0, len = inputs.length; i < len; i++) {
if (inputs[i].type.toLowerCase() === "text") {
stringBuffer.push(inputs[i].value);
}
}
str = stringBuffer.join(""); // str contains concatenated values of all inputs
}
Try this:
function processFormData()
{
var len= document.getElementsByTagName('input').length;
var str = '';
for(i=0;i<len-1;i++)
{
str += document.subscribe[i].value;
}
alert(str);
}
I have made a page using jquery, and on load it selects the first text field automatically. I want it to then move to the next field when the ENTER key is pressed.
$('.barcodeField input').bind('keyup', function(event) {
if(event.keyCode==13){
$("this + input").focus();
}
});
I can't find anything that works on the net. And I've scoured the forums.
I've created a little function which can do what you need. This is the version I use so you may need to change the class names but you should get the idea.
<script type="text/javascript">
$(document).ready(function(){
$(".vertical").keypress(function(event) {
if(event.keyCode == 13) {
textboxes = $("input.vertical");
debugger;
currentBoxNumber = textboxes.index(this);
if (textboxes[currentBoxNumber + 1] != null) {
nextBox = textboxes[currentBoxNumber + 1]
nextBox.focus();
nextBox.select();
event.preventDefault();
return false
}
}
});
})
</script>
So basically:-
Get all the input fields matching .vertical
Find which is the current text box
Find the next one
Set the focus on that one
You should use:
$(this).next('input').focus();
try this:
(function($){
$.fn.enterNext = function(){
var _i =0;
$('input[type=text], select',this)
.each(function(index){
_i = index;
$(this)
.addClass('tab'+index)
.keydown(function(event){
if(event.keyCode==13){
$('.tab'+(index+1)).focus();
event.preventDefault();
}
});
})
$( "input[type=submit]",this ).addClass('tab'+(_i+1));
}})(jQuery);
for use:
$('form.element').enterNext();
in my case this is the best solution in that I got because the function .next() is strict with elements outside their branch DOM.
The best way is to force an index.
and sorry for my bad English...
Basically, you just need top have the DOM elements in some structure so that you can select the next one. I'd suggest exploiting tabindex, but anything that let's you have a defined order will work.
Here is the solution I came up with. The issue I had was that I needed to maintain tabindex, i.e. it had to function exactly that same as hitting tab. It uses both underscore and jquery.
I've left in my debugging code:
try {
var inputs = $("input[id^=tpVal-]");
var sortedInputs = _.sortBy(inputs, function(element){
var tabIndex = $(element).attr('tabindex');//debugging
var id = $(element).attr('id');//debugging
console.log(id +" | "+ tabIndex +" | "+ $(element));//debugging
return parseInt($(element).attr('tabindex'));
});
$(sortedInputs).each(function (index, element) {
$(element).keyup(function(event){
if(event.keyCode==13) {
var $thisElement = $(element);//debugging
var nextIndex = index+1;//debugging
var $nextElement = $(sortedInputs[nextIndex]);
var thisId = $thisElement.attr('id');//debugging
var nextId = $nextElement.attr('id');//debugging
console.log("Advance from "+thisId+" to "+nextId);//debugging
if($nextElement!=undefined) {
$(sortedInputs[index + 1]).focus();
}
}
});
});
} catch (e) {
console.log(e);
}

I am looking to call my clear() JS function to clear the text values in some input fields on my webpage, but for some reason, the function doesn't appear to be called correctly. I believe this may be a scope issue, but I'm not sure.
Here is my markup, script and styling kept together for ease-of-use currently, but will be mended once scripting is finalized:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

function calculateQuad()
{
var inputa = document.getElementById('variablea').value;
var inputb = document.getElementById('variableb').value;
var inputc = document.getElementById('variablec').value;
root = Math.pow(inputb,2) - 4 * inputa * inputc;
root1 = (-inputb + Math.sqrt(root))/2*inputa
root2 = (-inputb + Math.sqrt(root))/2*inputa
document.getElementById('root1').value = root1;
document.getElementById('root2').value = root2;
if(root<'0')
{
alert('This equation has no real solution.')
}
else {
if(root=='0')
{
document.getElementById('root1').value = root1
document.getElementById('root2').value = 'No Second Answer'
}
else {
document.getElementById('root1').value = root1
document.getElementById('root2').value = root1
}
}
}
function clear()
{
document.getElementById('variablea').value = "";
document.getElementById('variableb').value = "";
document.getElementById('variablec').value = "";
}
</script>
<style>

You must rename the 'clear' method. Try naming it 'clearFields' or something. (;
Also, if you only want to reset the form fields you can also do this:
onClick="this.form.reset()"
You can avoid the issue with function naming entirely by using:
document.getElementById("calculate").onclick = function () {
...
};
document.getElementById("erase").onclick = function () {
...
};
This is actually a preferred method of adding event handlers by web developers because it avoids cluttering the HTML code with inline snippets of JavaScript while retaining cross-browser compatibility.
