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 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 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 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.
You can see in the paper form attached what I need to convert into a web form. I want it to show the check boxes and disable the input fields unless the user checks the box next to it. I've seen ways of doing this with one or two elements, but I want to do it with about 20-30 check/input pairs, and don't want to repeat the same code that many times. I'm just not experienced enough to figure this out on my own. Anyone know anywhere that explains how to do this? Thanks!
P.S. Eventually this data is all going to be sent through an email with PHP.
I don't think this is a good idea at all.
Think of the users. First they have to click to enter a value. So they always need to change their hand from mouse to keyboard. This is not very usable.
Why not just give the text-fields? When sending with email you could just leave out the empty values.
in your HTML :
//this will be the structure of each checkbox and input element.
<input type="checkbox" value="Public Relations" name="skills" /><input type="text" class="hidden"/> Public Relations <br/>
in your CSS:
.hidden{
display:none;
}
.shown{
display:block;
}
in your jQuery:
$('input[type=checkbox]').on('click', function () {
// our variable is defined as, "this.checked" - our value to test, first param "shown" returns if true, second param "hidden" returns if false
var inputDisplay = this.checked ? 'shown' : 'hidden';
//from here, we just need to find our next input in the DOM.
// it will always be the next element based on our HTML structure
//change the 'display' by using our inputDisplay variable as defined above
$(this).next('input').attr('class', inputDisplay );
});
Have fun.
Since your stated goal is to reduce typing repetitive code, the real answer to this thread is to get an IDE and the zen-coding plug in:
