I have a form with a few input fields, I only want to show a div when all the input fields got content, when one of the input fields has no content the div should disappear again.
I made it work with one input field, but how do I get it to work when all the input fields are filled in (don't know if its a good clean way?):
$(function () {
$('input').change(function() {
$('.next').toggle($(this).val().length !== 0);
}); });
Fiddle:
http://jsfiddle.net/uQyH9/19/
Try this : http://jsfiddle.net/uQyH9/21/
$(function () {
var _cached=$('input');
_cached.change(function() {
if (_cached.filter(function (){return $(this).val().length }).length==_cached.length)
$('.next').show();
else
$('.next').hide();
});
});
You can use a filter function to check that all the input are filled.
Code:
$(function () {
$('input').change(function () {
$('.next').toggle($("input").filter(function () {
return this.value === "";
}).length === 0)
});
});

UPDATE
You can check the value of the elements by type by cheking type attribute.
Code:
$(function () {
$('input').change(function () {
$('.next').toggle($("input").filter(function () {
var myType=$(this).attr("type");
if (myType === "checkbox") return !$(this).is(":checked");
if (myType==="radio"){
var myName = $(this).attr("name");
if (myName==="") return !$(this).is(":checked");
return $('input[name='+ myName +']:checked').length===0
}
return this.value === "";
}).length === 0)
});
});

Loop over the inputs. If you find one that isn't filled in, then hide the DIV. If you don't, show the DIV.
$('input').change(function() {
var allFilled = true;
$('input').each(function() {
if (this.value === '') {
allFilled = false;
return false; // Terminate the loop
}
}
$('.next').toggle(allFilled);
});

I developed a function that keeps the submit disabled until filling all the fields. The function works, but when I create two more users the submit button enables before filling the fields; my function works only once.
The button is working and the data is saved, but the submit button is enabled before filling the fields.
$(document).ready(function () {
$('#myForm input').keyup(function () {
var empty = false;
$('#myForm input').each(function () {
if ($(this).val().length == 0) {
empty = true;
}
});
if (empty) {
$('#btnsave').attr('disabled', 'disabled');
} else {
$('#btnsave').attr('disabled', false);
}
return empty;
});
});
i think you create new inputs dynamically, then try this:
$('#myForm').on('keyup', 'input', function () {
var empty = false;
$('#myForm input').each(function () {
if ($(this).val().length == 0) {
empty = true;
}
});
if (empty) {
$('#btnsave').attr('disabled', 'disabled');
} else {
$('#btnsave').attr('disabled', false);
}
return empty;
});
});
Right now the button shows when input is added to the input field, but if I remove the input the button doesn't hide.
My only idea for a solution is to divide the function into 2 seperate ones.
That is, one that adds the input to the input field on click, and then another functions that keeps track of input.val, and controls the hide/show effect of the button.
Would that be a better way of doing it?
$("#peopleInPopup").on('click', '.list-group-item', function() {
var peopleName = $(this).children("span").text();
var peopleID = $(this).children("span").attr("class");
var input = $("#friendsNames");
input.val(input.val() + peopleName + "");
if (input.val().length === 0) {
$("#checkButton").toggle(false);
console.log("button should NOT display");
} else {
console.log("button should display");
$("#checkButton").toggle(true);
}
$("#checkButton").click(function() {
var newParticipants = input.val();
socket.emit("addParticipantsToConversation", newParticipants);
$("#chatToInfo").append(", ", input.val());
$("#friendsNames").val("");
$(":mobile-pagecontainer").pagecontainer("change", $("#pagefour"), {
transition: "slidedown"
});
});
});
Just use show and hide from jQuery instead, perhaps? I assume you want this to happen as the input is changing, so I've thrown in keyup (could use onChange or alternatives).
Tweaking your code slightly...
$('input').on('keyup', function (event) {
let value = event.target.value;
if (value && value !== '' && value.length > 0) {
$('#myButton').show();
} else {
$('#myButton').hide();
}
})
With a markup...
<input id='input' />
<button id='myButton'>GO</button>
And some sort of base style...
#go {
display: none;
}
Do the trick?
I actually just found a solution to my problem. The code below makes it work:
$("#peopleInPopup").on('click', '.list-group-item', function(){
var peopleName = $(this).children("span").text();
var peopleID = $(this).children("span").attr("class");
var input = $("#friendsNames");
input.val(input.val() + peopleName + "");
$("#checkButton").toggle(true);
$("#friendsNames").on('input', function(event) {
if (this.value.length === 0) {
console.log("Works!");
$("#checkButton").toggle(false);
console.log("button should NOT display");
} else {
console.log("button should display");
$("#checkButton").toggle(true);
}
});
$("#checkButton").click(function(){
var newParticipants = input.val();
socket.emit("addParticipantsToConversation", newParticipants);
$("#chatToInfo").append(", ",input.val());
$("#friendsNames").val("");
$(":mobile-pagecontainer").pagecontainer("change", $("#pagefour"), { transition: "slidedown" });
});
});
I have a few input textfields on a screen and some hide at certain time. I am trying to disable them when they are hide().
I have tried .prop and .attr to disable, but during the check it is still treating them like they are there.
Any suggestions?
So on my button function I have this variable that checks all the boxes to see if nothing is in it
var emptyTextBoxes = $('input:text').filter(function () {
return this.value === "";
});
You can use is() with the :hidden selector for this:
var emptyTextBoxes = $('input:text').filter(function () {
return !$(this).is(':hidden') && this.value === "";
});
Or :not:
var emptyTextBoxes = $('input:text:not(:hidden)').filter(function () {
return this.value === "";
});
Use .is()
var emptyTextBoxes = $('input:text').filter(function () {
return !$(this).is(':hidden') && this.value === "";
});
I'm trying to generate html on the fly with javascript. I'm binding on the click of buttons on my page. There are multiple buttons on my page which are causing my elements to be bound multiple times which produces the desired results to appear in the amount of times the button has been clicked.
My question is there something that can check if a element is already bound in jquery? If so, how do I incorporate that with the .live() function in jquery.
Here is my code:
$(document).ready(
function () {
$(':button').live("click", ".textbox, :button", function () {
alert("binding");
$(".textbox").click(function () {
defaultVal = this.defaultValue;
if (this.defaultValue) {
this.value = "";
}
});
$(".textbox").blur(function () {
if (this.value == "") {
this.value = defaultVal;
}
});
$('[name="numsets"]').blur(function () {
if (!parseInt(this.value)) {
$(this).val("you need to enter a number");
}
});
$('[name="weightrepbutton"]').click(function () {
var $numsets = $(this).parent().children('[name="numsets"]');
if ($numsets.val() != "you need to enter a number" && $numsets.val() != "Number of Sets") {
var numbersets = parseInt($numsets.val())
repandweight.call(this, numbersets)
$(this).hide();
$numsets.hide();
}
})
});
});
The problem is line 4, every time a button is clicked, all functions that were previous bound seem to be bound to the same function twice, which is a problem.
Thanks for the help!
You are doing it twice ! One inside another. Take out the outer binding and it should work
$(document).ready(function () {
$(document).on("click",".textbox",function () {
defaultVal = this.defaultValue;
if (this.defaultValue) {
this.value = "";
}
});
$(document).on("blur",".textbox",function () {
var item=$(this);
if (item.val() == "") {
item.val(defaultVal);
}
});
$(document).on("blur","input[name='numsets']",function () {
var item=$(this);
if (!parseInt(item.val())) {
item.val("you need to enter a number");
}
});
$(document).on("click","input[name='weightrepbutton']",function () {
var $numsets = $(this).parent().children('[name="numsets"]');
if ($numsets.val() != "you need to enter a number" && $numsets.val() != "Number of Sets") {
var numbersets = parseInt($numsets.val())
repandweight.call(this, numbersets)
$(this).hide();
$numsets.hide();
}
})
});
if you are using jQuery 1.7+ version, consider switching to jQuery on instead of live.
EDIT: Updated live to on as OP mentioned it in the comment.
I found this useful little method of displaying field titles within the text fields themselves.
http://viralpatel.net/blogs/2009/09/default-text-label-textbox-javascript-jquery.html
Only problem is that if the fields aren't completed by the user then the title values get submitted.
Could anyone tell me how to add a onsubmit check to make sure we don't submit default text?
This is the javascript:
$('input[type="text"]').each(function () {
this.value = $(this).attr('title');
$(this).addClass('text-label');
$(this).focus(function () {
if (this.value == $(this).attr('title')) {
this.value = '';
$(this).removeClass('text-label');
}
});
$(this).blur(function () {
if (this.value == '') {
this.value = $(this).attr('title');
$(this).addClass('text-label');
}
});
});
Many thanks...
Something like the following should work:
$('form').submit(
function(e){
$(this).find('input, select, textarea').each(
function(){
if ($(this).val() == this.title){
$(this).val(''); // removes the value
// or prevent form submission:
// return false;
}
});
});
