I have an Input element in HTML (and a Javascript template) with empty Value. Throught AJAX and JQuery, I update the said value to a list of words split by comma. Each word should become green retangulars with an 'X' to remove it from the field. The same list of words works perfectly when I write it down in the code.
The problem is that when I put this very same string in the Value attrib. using JQuery, it just doesn't work properly. I just get plain text, and those fancy green retangulars only appear when I click inside the input field and hit TAB key. Then They become one item only and when I finally click to remove it, then they got split(!).
I have already tried using fadeOut() and fadeIn() and refresh method. Did not work.
Any ideas about this?
HTML:
<input id="tags_1" type="text" class="tags form-control" value="" />
AJAX/JQUERY:
var tags_x = tags_x.replace(/\,/g, ', ');
var tags_x = tags_x.split(',');
$('#tags_1').val(tags_x);
$('#tags_1').attr('value', tags_x);
$('#tags_1').fadeOut();
$('#tags_1').fadeIn();
Your id of the input is tags_1 but you are selecting it like #tags_1_tag. Why is that? I think maybe that could be the reason.
And by the way when you use var tags_x = tags_x.split(','); tags_x is an array now. If you want to put it in a value convert it to a string and then try to put it in the value attr. You can see an example below:
var new_x = tags_x.join('')
$('#tags_1_tag').val(new_x);

I'm trying to prepare my first Greasmonkey script (with no experience in javascript/websites technologies) and I have problem with selecting field on a page. It is:
<input data-testid="user/fullName" autocomplete="name" class="form-control u-text-normal">
I've tested:
document.querySelectorAll("input.form-control");
document.querySelectorAll("input.form-control.u-text-normal");
document.getElementById("user/fullName").value
but non of them is returning what I need... and what I need is possibility to fill that form field with the script. Could you help, please?
EDIT:
The methods given in the following answers I try to run in the browser console and they do not return me any element. Maybe someone could try to run it and tell me what I'm doing wrong? The website is a shopping cart on the pizza site :) But to see it you need to add pizza to cart ("Do koszyka") for a minimum of 20 zł and then go to payment ("Do kasy"). Then the first field "Imie i nazwisko" is what I would like to fill at the beginning.
If you need to get a single element, give the html element an id example:
<html>
<input id='id_here'data-testid="user/fullName" autocomplete="name" class="form-control u-text-normal">
</html>
then get the element using
document.getElementById('id_here');
For multiple elements that share the same class you could use the query selector
document.querySelector('.form-control')
Is this what you wanted?
var example = document.querySelector('.form-control').value;
document.write(example);
<input data-testid="user/fullName" autocomplete="name" class="form-control u-text-normal" value="test">
If you only want to select this element, use the most specific thing, in this case data-testid:
var x = document.querySelectorAll("[data-testid='user/fullName']")
console.log(x[0].value)
to select the element (here we select with the class and the data property to be the most accurate) =>
var element = document.querySelector('.form-control[data-testid="user/fullName"]');
After if you want add some value in this input =>
element.value = "My_value";
Regards
You can add 'id' or select your field by querySelector
let input = document.querySelector('[data-testid="user/fullName"]')
input.value='abc';
myField.value += '123';
<input id="myField" data-testid="user/fullName" autocomplete="name" class="form-control u-text-normal">
Update
I try my method and it works pizza site which you mention in your question update:
But it looks like that console 'see' dom input element after you find it using right click> inspect element - strange
I know it's simple and there's probably something wrong with my syntax but I just don't understated it. I'm talking about the following:
//declaration of a string
var str_input = "";
//this is supposed to get the new inputs and to store them in str_input
$(document).ready(function(){
str_input = $('input[name=po]').val();
});
//this is on html side, this should make an input field where the user to type in the needed
<input type"text" name = 'po' id="po" value="asd">
That's it, can you help me to sort it out? The problem so far is that str_input is undefined regardless of what is written in the input, though, it saves its initial value.
Your html tag is invalid:
<input type"text" name = 'po' id="po" value="asd">
Should be:
<input type="text" name = 'po' id="po" value="asd">
// ^ Missing this character (=)
Ok, Now I understood, you can do 2 things, first, you can create a button than when the user clicks it calls the function to store the value in the variable like this:
var str_input = "";
//this is supposed to get the new inputs and to store them in str_input
$(document).ready(function(){
$("#MyButton").click(function(){
str_input = $('input[name=po]').val();
})
});
//this is on html side, this should make an input field where the user to type in the needed
<input type"text" name = 'po' id="po" value="asd">
<input type="button" id="MyButton" value="Click Here" />
Or the blur function when the user lose focus of the input text like this:
var str_input = "";
//this is supposed to get the new inputs and to store them in str_input
$(document).ready(function(){
$('input[name=po]').blur(function(){
str_input = $('input[name=po]').val();
})
});
//this is on html side, this should make an input field where the user to type in the needed
<input type"text" name = 'po' id="po" value="asd">
Ok, so here is the solution, though it's a little bit in "from Alf to Alf" style. So, yes, the code I've posted in the main post uses correctly the 'by default' value of the input but the problem comes from that nothing is checking for further changes in the input text field. I'm using $(document).ready... which as far as I know runs during the web project is opened and of course enables the use of some jquery methods within it. There is an interesting function called .change() which actually put the whole thing up for me. Take a glance at the following:
$(document).ready(function(){
$('input[type="text"]').change(function(){
str_input = $('input[name=polynom]').val();;
});
str_input = $('input[name=polynom]').val();
});
The second, third and fourth line make the magic actually, where the code in the .change() method updates str_input on each time a change have appeared in the input box field, whereas the str_input = $('input[name=polynom]').val(); outside of change() takes into account the initial value of the input. That's it... I knew I was forgetting something and yeah...
P.S. Another approach is to use a function and a button (a.k.a. an event-triggered function) which to 'update' the str_input on event. For this way check the post bellow this one.
I have googled and looked throughout the whole documentation and could not figure out why value of input text is not shown. I am using FireFox latest version and below is what I have done so far.
<input name="amount" class="easyui-validatebox" id="d_amount" value="">
In regular html or php page we can give value="300" to set default value, but in EasyUI, it is not possible. So I was thinking possible alternative like below:
<script>
var m = '300';
document.getElementById("d_amount").value.innerHTML=m;
</script>
Nothing is shown and I am not getting any error. Any EasyUI expert, please help me.
NOTE: this input field is inside the dialog
To set the default value, you have to set the value attribute. However, that does not necessarily update the value property so you need to do both. So given:
<input name="amount" class="easyui-validatebox" id="d_amount" value="">
set the default value by setting the value attribute:
var input = document.getElementById('d_amount')
input.setAttribute('value', 'whatever');
now set the value property:
input.value = 'whatever';
Note that you can also get a reference to the input as a member of the form that it's in:
var input = document.formName.d_amount;
Use the below code
$("#d_amount").numberbox({
min:0,
precision:2,
value:300
})
Reference : numberbox
Or try this one
$("#d_amount").textbox({
buttonText:'Search',
iconCls:'icon-man',
iconAlign:'left',
value:"300"
});
Reference : textbox
use this code to set the value inside $(document).ready(function(){}
....
$("#d_amount").numberbox('setValue','300');
....
if still not working, just try to set name and id as the same name and id
<input name="d_amount" class="easyui-validatebox" id="d_amount" value="">
I am always working with this numberbox and it's working
I have found your thread because I am also having the same issue and I have just across this thing today. Your case is a little bit different (maybe) then my case because you want to set the default which can be changed by the user later (I believe). In my case, the value will be fixed (will not be changed) so I have applied a trick and hopefully it can give some ideas to you and others who are having same issue. Please refer below:
In first page says pageA.php:
<select name="myThing" id="myThing">
<option value="Your Desired Value" selected="selected">Something</option>
</select>
Still in the same page, under your $(document).ready( function(){ put the code below:
$("#myThing").val($("#myThing option:first").val());
That code is to make sure your desired value appears at the first row in the drop down. I say this because in EasyUI it seems when I use drop down and put single option, the first row will be blank and the second row will hold your input. So that is the trick to ensure your desired value appears on top and selected. Put the select under the form then during normal post, you will be able to get the value of it in the posted page. Enjoy. Thank you.
Suggestion: if your value can be changed by user, use placeholder and you can hide the default value from user using my trick.
try this
document.getElementById("d_amount").value=m;
you don't need innerHTML
I found the answer here. The trick is to use the code inside $(function(){});
$(function(){
var m=300;
$('#d_amount').textbox('setValue', m);
});
I too had this problem and it was solved using the following
First my input was in the form like this:
<input name="hostFirstName" id="hostFirstName" class="easyui-textbox">
I needed to load content from the db then pre-fill the input with this data so the user could edit the content.
I used the following javascript.
NOTE: i didn't hide this away inside an anonymous function() and it is working. I tested this first from the F12 console to make sure it was working before changing my code.
//populate with existing data
$('#hostFirstName').textbox('setValue', "Is this working?");
The docs on jeasyui.com don't provide this example when you look at the textbox api reference. But they do provide an example when looking at the combobox (http://www.jeasyui.com/documentation/index.php#) the combobox and textbox use the same setValue method.
Hopefully this works for you like it does for me.
I'm very new to jQuery and have been stumped by particular issue. I am dynamically adding 2 checkbox fields to a screen form using the code below:
var summon_search = "<br><br><br><label for='summon_search'>Search this resource from compatible products*</label><input type='checkbox' id='summon_search' >";
var summon_link = "<br><br><label for='summon_link'>Link direct from content items in compatible products*</label><input type='checkbox' name='summon_link'>";
$(summon_search+summon_link).insertAfter("#jstor_selection");
However I have had limited success when I want to remove these fields AND labels (which is dependant on another value) and replace them with new fields. The code below shows my best attempt so far. It does appear to remove the labels and first field, but for some reason the last field remains. Could someone please advise if they can spot anything I've done wrong, or perhaps supply a better example of handling this ?
if ($("#summon_search").length > 0 ) {
//Removal of Label and Field (Attempted)
$("label[for=summon_search]").remove();
$("label[for=summon_link]").remove();
$("#summon_search").remove();
$("#summon_link").remove();
Any feedback much appreciated.
Change name='summon_link' to id='summon_link', because #summon_link expects an id.
if you see your code the summon_link variable give it a id instead of name like in the summon_search variable
name=summon_link change it to id='summon_link'
if your intention is to add these HTML string after object with Id 'jstor_selection', you can use like this
$("#jstor_selection").append(summon_search+summon_link);
you should give the for= value in quotes.
EDIT: to remove extra <br>, normally it is suggested not to use <br>
$("label[for='summon_search']").prev('br').remove()
$("label[for='summon_link']").prev('br').remove()
$("label[for='summon_search']").remove();
$("label[for='summon_link']").remove();
also in the suman_link input element you have given as name
<input type='checkbox' name='summon_link'>
either change this to
<input type='checkbox' id='summon_link'/>
or
$("#summon_link").remove();
to
$("input[name='summon_link']").remove();
I have just begun playing with MooTools, and I don't understand why the following happens:
var input = new Element('input');
input.set('type','text');
input.set('value','this is the value');
console.log(input);
results in: <input type="text">, so setting the value hasn't worked.
But if I do this:
var input = new Element('input');
input.set('type','text');
input.set('someValue','this is the value');
console.log(input);
I get the expected result of <input type="text" somevalue="this is the value">.
Am I overlooking something, is what I am trying to do not allowed, is this a bug in Chrome (11.0.696.71, OS X) or am I doing something else wrong?
Update: thanks for your answer! You are right, the value is actually being set; console.log(input.get('value')) gives back the proper value and I can see the value in the input field when I append the input object to the DOM.
Apparently, the value setting is just not reflected as an attribute of the HTML element, but only stored internally.
Are you sure the value isn't being set?
What do you get when you call: input.get('value')
I tested this (in firefox) and even though the console just logs <input type="text"> the value does in fact get set. Try adding the element to the page and you'll see it :)
I've had a similar problem with this 'red herring' which I've since solved, and thought I'd share.
I'm trying to make certain cells of a table row editable when the user clicks on the row:
var cells = this.getElements("td");
for (var ix=0;ix<cells.length; ix++){
if (cells[ix].hasClass("edType_text")){
var celltext = cells[ix].get("text");
cells[ix].set('text','');
var editTag = new Element ('input',{type:'text','value':celltext});
editTag.inject(cells[ix]);
}
}
This seemed to work OK but when I clicked on the cell I couldn't edit it. Firebug and Chrome tools showed the added input tag as
<input type='text'>
instead of the expected:
<input type='text' value='xxxxxx' />
However this is perfectly normal as commented on above.
Spotted the 'deliberate' error ?
Of course when I clicked on the input field it triggered the mouse event on the row again, thus preventing me getting at the input!!!! :-{
To avoid this just add this line of code at the end of the if block:
editTag.addEvent("mousedown",function(event){event.stopPropagation();});
