I'm trying to save whole page as HTML file included all already written values into inputs. I tried this:
$("#content").html();
but it wont save values from inputs.
$("#content").get(0).outerHTML;
$("#content").prop('outerHTML');
Works same but still not save values of inputs. I need function which save everything on the page.
You need to set up each input values first:
$('#content input').each(function() {
$(this).attr('value', $(this).val());//set up all the input values
});
var html = $('#content').html(); //now from here you can get input values
You could try:
$("html").html();
If you want to also capture the hmtl tags you could concatenate them to the html like this:
function getPageHTML() {
return "<html>" + $("html").html() + "</html>";
}
you have save the inputs values in some variable like
var input=$("#input-id").val()
When an input is changed by the user it's .value is being changed. .value is not in the DOM, it's in the JS. So, what you need to do is transfer the .value to value= in order to be able to get it in the string. Here is how to accomplish it:
$('input').each(function(index, input){input.setAttribute('value', input.value)});
Now try to get the HTML ;)
PS: You could also modify the selector here, not to get all the inputs (like type="password").

Is it possible to assign HTML text within an element to a JavaScript variable? After much Googling, I note that you can assign HTML elements to a variable, but I want the actual text itself.
Details about my goal:
I am currently working on a CRUD application, and with the click of a delete button, a modal will display and ask the user for confirmation before deleting the record. Once the button has been clicked, I want to retrieve HTML text within a specific element used for AJAX call data. However, what I have tried so far is not being logged to the console; even when I change the global variable to var deleteLocationID = "test"; I doubt the modal displaying will affect the click function?
The code:
var deleteLocationID;
$("#deleteLocationBtn").click(function () {
deleteLocationID = $(document).find(".locationID").val();
console.log(deleteLocationID);
});
What I have tried so far:
Changing "deleteLocationID = $(document).find(".locationID").val();" to the following variations:
deleteLocationID = $(document).find(".locationID").html();
deleteLocationID = $(".locationID").val() / deleteLocationID = $(".locationID").html();
deleteLocationID = document.getElementsByClassName("locationID").value;
Any help would be much appreciated.
Use the text() method from JQuery, with this you can get the text inside of your element.
Use this way, it may help you:
deleteLocationID = $(document).find(".locationID").text()
Here is example of getting text from class element:
$('.locationID').text()
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<div class="locationID">45</div>
It depends on the type of element you are trying to find your value.
for input types you can find the value by .val() in jQuery like:
$(document).find(".locationID").val();
you can grab innerHTML of the element by .html() in jQuery like:
$(".locationID").html();
but if you want to grab innerText of an element you can use .text() in jQuery like:
$(".locationID").text();
How to get the html of element itself using Jquery html. In the below code I would like get the input element inside div using JQuery as shwon below
<div id="content">content div</div>
<input type='text' id="scheduledDate" class="datetime" />
$(function() {
console.log($('#scheduledDate').html('dsadasdasd'));
$('#content').html($('#scheduledDate').html());
});
EDIT:
Can I get the $("#scheduledDate") as string which represent the real html code of the input box, because my final requirement is I want to pass it to some other SubView( I am using backboneJS) and eventually use that html code in a dust file.
My original requirement was to get that input field as string so that I can pass it to some other function. I know, if I keep it inside a DIV or some other container, I can get the html by using .html method of JQuery. I dont want use some other for that purpose. I am just trying to get html content of the input box itself using it's id.
If you want to move the input element into div, try this:
$('#content').append($('#scheduledDate'));
If you want to copy the input element into div, try this:
$('#content').append($('#scheduledDate').clone());
Note: after move or copy element, the event listener may need be registered again.
$(function() {
var content = $('#content');
var scheduledDate = $('#scheduledDate');
content.empty();
content.append(scheduledDate.clone());
});
As the original author has stated that they explicitly want the html of the input:
$(function() {
var scheduledDate = $('#scheduledDate').clone();
var temporaryElement = $('<div></div>');
var scheduleDateAsString = temporaryElement.append(scheduledDate).html();
// do what you want with the html such as log it
console.log(scheduleDateAsString);
// or store it back into #content
$('#content').empty().append(scheduleDateAsString);
});
Is how I would implement this. See below for a working example:
https://jsfiddle.net/wzy168xy/2/
A plain or pure JavaScript method, can do better...
scheduledDate.outerHTML //HTML5
or calling by
document.getElementById("scheduledDate").outerHTML //HTML4.01 -FF.
should do/return the same, e.g.:
>> '<input id="scheduledDate" type="text" value="" calss="datetime">'
if this, is what you are asking for
fiddle
p.s.: what do you mean by "calss" ? :-)
This can be done the following ways:
1.Input box moved to the div and the div content remains along with the added input
$(document).ready(function() {
var $inputBox = $("#scheduledDate");
$("#content").append($inputBox);
});
2.The div is replaced with the copy of the input box(as nnn pointed out)
$(document).ready(function() {
var $inputBox = $("#scheduledDate");
var $clonedInputBox = $("#scheduledDate").clone();
$("#content").html($clonedInputBox);
});
Div is replaced by the original input box
$(document).ready(function() {
var $inputBox = $("#scheduledDate");
$("#content").html($inputBox);
});
https://jsfiddle.net/atg5m6ym/4485/
EDIT 1:
to get the input html as string inside the div itself use this
$("#scheduledDate").prop('outerHTML')
This will give the input objects html as string
Check this js fiddle and tell if this is what you need

I am pretty new in JQuery and I have the following problem.
I have create this JQuery function that when the user select a file into an input tag having id=rendicontoAllegato it put the name of this file into an hidden div having id=nomeDocumentoRendicontazione into my page
$(document).ready(function() {
$("#rendicontoAllegato").change(function() {
alert("DOCUMENTO dopo selezione: " + $("#nomeDocumentoRendicontazione").text());
var selectedFileName = $("#rendicontoAllegato").val();
$('#nomeDocumentoRendicontazione').append(selectedFileName);
});
});
It works fine but the only problem is that if I first select something asfile1.txt and then select another file as file2.txt into the div having id=nomeDocumentoRendicontazione I will have the concatenation of the 2 files name.
So I will have something like file1.txtfile2.txt and it is not good for me.
How can I replace the value of the div having id=nomeDocumentoRendicontazione instead to append a new value inside it?
You can use the .text() fn if you are dealing with with your data to be inserted as text or .html() fn if you are dealing with html to be replaced
$('#nomeDocumentoRendicontazione').text(selectedFileName);
Or
$('#nomeDocumentoRendicontazione').html(selectedFileName);
Use html() instead of append().
$(document).ready(function() {
$("#rendicontoAllegato").change(function() {
alert("DOCUMENTO dopo selezione: " + $("#nomeDocumentoRendicontazione").text());
var selectedFileName = $("#rendicontoAllegato").val();
$('#nomeDocumentoRendicontazione').html(selectedFileName);
});
});
You have to use
$('#nomeDocumentoRendicontazione').html(selectedFileName);
it will replace the already present HTML of that. OR you can use
$('#nomeDocumentoRendicontazione').text(selectedFileName);
it will do the same but append your data as text.
I have multiple <textarea>, sometime they are blank and sometime they are filled with text.
I want to insert a simple text code such as "<check>" which will automatically change to a check (\u2713).
Presently, my code is like this:
<textarea name="1-S" onchange="check(this.value)">
<check> //an input written by a user
</textarea>
<textarea name="1-NI" onchange="check(this.value)">
<check> //an input written by a user
</textarea>
<textarea name="1-C" onchange="check(this.value)">
<check> //an input written by a user
</textarea>
(This block of <textarea> gets repeated, but of course, with different name in each one.)
<script type="text/javascript">
function check(str){
var res = str.replace("<check>", "\u2713");
????
}
</script>
The output will then replace <check> into actual check symbol (\u2713)
The challenge is, I don't want to have to add ID to every <textarea> and then write a script for each one. So is there a way for me to use this one script to apply to all <textarea>???
Many thanks in advance!
You could use the getElementsByTagName method to create an array of your text area tags.
Since you're using jQuery:
$("textarea").each(function(index, textarea) {
// do replacement here
});
Note that you need to use HTML entities to put <check> into a textarea: <check>
Also, you can put a checkmark in without any Javascript like this: ✓
Yes. You can bind an event handler to all elements of a type using jquery.
$('textarea').on('change', function() {
var text = $(this).val();
if (text.match(/\<check\>/)) {
$(this).val(text.replace(/\<check\>/, "\u2713"));
}
});
The benefit of doing it this way is that you can remove your inline 'onchange' handlers from the html and consolidate your validation logic strictly to JavaScript.
To replace the actual textarea content you need to update the value of the textarea with the result of your String-replace regexp. var text = $(this).val() is just assigning the content of the textarea to the variable text, it's not a reference to the innerHTML portion of your textarea.
On a sidenote if you'd like to allow users to use shortcodes in a form, prefer square bracket syntax, e.g., [check].
I have a JS file CharacterSelection where a user can select an avatar and type their name into a textarea.
Now I want to set a text div in an html file to the contents of the textarea. I will use it to display the player's name at a specific location on the screen.
I know that I can set a div to a text, such as: <div id ="statSheetExitButton">Exit</div> will show "Exit" (style and location depending on css)
I'm wondering if there is any way to put a String variable in there, since I will not know what name the player enters.
I grab the textarea's contents using var name = $("#nameTextBox").val();
I'm thinking that saying <div id ="playerName">name</div> will display the text "name".
Is there a way to accomplish my goal?
$("#nameTextBox").change(function(){
$("#playerName").html($(this).val());
});
This will attach an event handler to the textbox so everytime the name changes the div is updated.
Here is a working example. http://jsfiddle.net/2NkTb/
Please note that for the onchange event you must tab out of textbox or the textbox must lose focus
var name = $("#nameTextBox").val();
$("#playerName").html(name);
Do this:
var name = $("#nameTextBox").val();
$('#playerName').text(name);
You could do something like this which will replace the html of the tag with your JavaScript string:
$('#playerName').html(myNameVar);
Other than that, I don't think you can directly inject JavaScript variables like you would in a template language.
Try:
$('#playerName').html($("#textbo").val());
var playerName = 'John Dow'
document.getElementById('playerName').innerHTML=playerName
You need to set the property innerHTML of you div element.
$("playerName").innerHTML = name;
