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 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 am using localStorage where in I am able to store in previous page and retrive it in this page. (Checked it using alert).
name12=localStorage.getItem("content");
Now my requirement is to display it into the input field and make it non-editable.
Please help me out with it. I have tried different things but I am not able to get it right.
Used onblur="localStorage.setItem(this.name, this.value) in the input tag
and also tried to use
if name_2.value = name12; in script tag
To make a field uneditable, you can use the html attribute disabled on the input field. http://www.w3schools.com/tags/att_input_disabled.asp
To set a default value for a field, you can use the html attribute value. In your case since the value is dynamic, you probably want do not want to do that inline in the html. One possible solution is to set the value attribute through javascript like below.
<script type="text/javascript">
var name2 = document.getElementById("name_2");
name2.value = localStorage.getItem("content");;
</script>
Set the value of an input field
You have to assign the value to input using javascript.
<input username" id="name_2" type="text" placeholder="name" name="name_2" required="required" autofocus="autofocus">
<script>
var n = "5"; // read from storage here
var inpt = document.getElementById("name_2");
inpt.value = n;
inpt.disabled = true;
</script>
There are many places to find this information. Try reading the jquery documentation when you get stuck. For example, here is a page that describes how to set the value of an input element. StackOverflow also has many questions about this topic. A quick google search brings up this question about setting the value of input elements. We can also find SO questions about disabling input elements easily, like this one.
I encourage that you attempt to use more resources to find what you need before bringing your questions here.
Based on the answers to the questions I linked, we can set the input and then disable it to keep the value from changing:
$('#input').val(name12);
$('#input').prop('disabled', true);
I have an input field that I want to make it readonly for the users, and only the admin can change it .
<input value="http://google.com" class="form-control" readonly></div>
if you want do this as other said, you must have a database gestion, anyway the code that you must have is like:
<input id ="label1" value="http://google.com" class="form-control" readonly></div>
<script type="text/javascript">
var isAdmin = "1" //this variable must be valorized with a flag or something that is supposed to be, for example 0 for users 1 for admins
if(isAdmin==1){
var checkVisible = document.getElementById("label1");
checkVisible.readOnly= false;
}
</script>
for sure it's not a professional solution but this can give to you and idea how it works
2 simple ways to do this.
1st you can incorporate javascript inside in your jsp. Then create function that would hide your the field that can be editted if the user is not admin.(Then show only the read-only or text field) Then show it otherwise which seemed a little complicated this way.
But anyway, 2nd is you can use jsp standard tag library or jstl.. use . It works like a switch with case statements :) for reference please see: http://www.tutorialspoint.com/jsp/jstl_core_choose_tag.htm
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 working on a dynamic form where you can add or delete fields, Here you can find the fiddle
The first button you find is Add Metric. From this the code generates:
Input Field Metric
Button Add Tag
Inside this field a user can add a tag with the button Add Tag, generated when you click add Metric. When you click Add Tag button, two fields are generated:
Input Field Id
Input Field Value
The Html code that I need to generate in order to serialize the entire form (this is not however the question point) will result like this:
<input type="text" name="metrics[0][name]" value="Text 0"> // Metric
<input type="text" id="TagId0" name=" "> //Tag Id
<input type="text" id="TagValue" name="metrics[0][tags][][0]">
Problem:
I need that (when I fill the field with id="TagId0") the value I select will go immediately to the field name with id="TagValue". This field must result like this:
Consider I write on TagId0 the word "hello", field will become:
<input type="text" id="TagValue" name="metrics[0][tags][hello][0]">
How, if it's possible, it can be done?
Thanks
You can use the change method to detect a change in the fields value. Then use the attr method to change the name. Hope I understood correctly. Here is the modified JSFIDDLE.
$(document).on('change', '#InputsWrapper .inputID', function(){
thisVal = $(this).val();
thisName = $(this).siblings('.inputVal').attr('name');
newName = thisName.replace('[tags][', '[tags][' + thisVal);
$(this).siblings('.inputVal').attr('name', newName);
});
Don't forget to press enter after change the field value :)
Edit: I also added two classes to the fields you are appending. .inputID and .inputVal. I hope this helps!
you can write id of field something like TagId-0 and some common class like tagfield,so that u can split the value to get the index an then access it using the class
$(".tagfield").keypress(function() {
var id=parseInt($(this).attr("id").split("-"));
$(this).siblings().attr("name","metrics["+id+"][tags]["+$(this).val()+"][0]");
});
