what the result looks like
I'm making a product inventory system; where I can simple change the value with number inputs, hit the checkmark, and be done. But I'm having trouble getting the specific value.
php:
<?php
$get_prod = $con->query("SELECT * FROM products");
while($get = mysqli_fetch_array($get_prod)){
echo '
<div class="prod-inv">
<div class="prod-inv-top">
<h1>'.$get['prod_name'].'</h1>
<h2>'.$get['prod_price'].'</h2>
</div>
<div class="prod-inv-body">
<img class="image-manage" src="'.$get['prod_cover'].'">
<input id="'.$get['prod_id'].'" type="number" class="num" value="1"/>
<button id="'.$get['prod_name'].'" class="btn search">✓</button></a>
</div>
</div>';
}
?>
jquery:
<script type="text/javascript">
$("button").click(function() {
var target = this.id;
var value = $(target).val();;
alert(value);
});
</script>
I've tried everything from form GET, to href links, now jquery. So far nothing has yelded results.

[1] Firstly, I'm not familiar with PHP, but it seems that closing anchor tag mistakenly presents in the markup:
<button id="'.$get['prod_name'].'" class="btn search">✓</button></a>
Or maybe opening anchor tag is missing...
[2] Secondly, in following line:
var target = this.id;
context "this" is currently clicked button, this code takes clicked button id and then in this line:
$(target)
you're taking currently clicked button DOM element by it's id, but it is already stored in "this"
[3] when you want to query element by id, you have to prepend it with hash "#":
$('#' + target)
So, you see the issue, when button is clicked, you take it's id, then find this button on the page again by it's id and then try to take .val() from a button (which actually does not have a value, it is not an input)
Suppose, you wanted to achieve following:
button is clicked -> find input near this button -> take value of this input
$('button').click(function () {
var value = $(this).closest('.prod-inv-body').find('input').val();
console.log(value);
});

I want to make a list in HTML and then the user selects the list and then do something with the selections.
For example. List of fruits. Apple bannana, grapes.
User selects grapes and if grapes is selected asked how many grapes?
I would like to know how i can do this in Javascript or Jquery

Use this code block. As simple as that,
//generates the list
var items = 'Apple, bannana, grapes';
var nHtml = '';
items = items.split(',');
items.forEach(function(v){
//trim() will remove the blank spaces
nHtml+='<li>'+ v.trim() +'</li>';
});
$('#itemList').append('<ul>'+ nHtml +'</ul>');
//detect click on the list item
$('li').click(function(){
var name = $(this).text();
var question = 'How many '+name+' ?';
$('#question').html('<span>'+ question +'</span><input type="text" id="answer" />')
});
//get the number feed into the text box
function getCount(){
var answer = $('#answer').val();
console.log(answer);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='itemList'></div>
<div id='question'></div>
<button onclick='getCount()'>Get Count</button>

I have a small project where i created text fields based on user input.
$('#arraySizeButton').click(function() {
var arraySize = $("#arraySize").val();
if(arraySize=='') {
alert("Enter Some Text In Input Field");
}else{
var count = arraySize;
var html = [];
while(count--) {
html.push("\<input type='text' id='inputTextField", count, "'>");
}
$('#inputTextFieldsarea').append(html.join(''));
}
});
I want to create a dynamic program based on above code and retrieve data from textfields to an array. Appreciate your help.

Did you mean this?
html.push("<input type='text' id='inputTextField"+count+"'/>");

What you should do is add a [] to the name of the input, to let the html form know that this is an array.
You should do something like that:
html.push("\<input name='field[]' type='text' id='inputTextField", count, "'>");
And using php to get the content of all the POSTed fields you could simply check
$_POST['field']
which is an array.
EDIT: IF you want to do this using jquery as you stated in your comment, then you could do it like that:
$('[id^="inputTextField"]').each(function() {
alert($(this).val());
});

I don't understand the concept of this function in Javascript [closed]

for example, you would have
<input id="searchbox" type="text" value="Type Here..." />
<button id="clickbait">Click Me</button>
<div id="emptydiv">sda</div>
<script type="text/javascript">
var clickthis="clickbait";
var searchinput=document.getElementById("searchbox").value;
var generate="emptydiv";
document.getElementById(clickthis).onclick=function () {
searchinput=document.getElementById("searchbox").value;
document.getElementById(generate).innerHTML=searchinput;
}
</script>
So this is pretty much just something to change the text in the empty div to whatever is in the text field when you click on the button but I don't understand the "idea" of what's going on here. I already set the var to a value so why do you need to grab the value again?
I can understand the other basics so far like document(refers to the whole page) then getelementbyid(refers to the element) and then on the click you want it to perform a function but everything after that is confusing.

I already set the var to a value so why do you need to grab the value
again?
When you set the searchinput value first before the onclick assignment, you fetched and assigned the value of searchinput at that time.
Inside the click event handler, you are getting the value in searchinput when the div is clicked so the value at that time might be different.

When its firing click event then searchinput=document.getElementById("searchbox").value;
that means searachinput is what everever typed in the input feild
and then that value is being reassigned to
document.getElementById(generate).innerHTML=searchinput;

`
When the button is clicked fire the event:
document.getElementById(clickthis).onclick=function ()
Get the value of 'searchBox':
searchinput=document.getElementById("searchbox").value;
Assign what ever was in the 'searchBox' as HTML in 'emptyDiv'
document.getElementById(generate).innerHTML=searchinput;
Just to note that:
searchinput=document.getElementById("searchbox").value;
Is actually redundant because you are already declaring it with the other vars.
So your code should look like this:
document.getElementById('clickbait').onclick=function () {
var searchinput = document.getElementById("searchbox").value;
document.getElementById('emptydiv).innerHTML=searchinput;
}
Or to make it even simpler and cut it down to 2 lines you could even use jQuery:
$('#clickbait').on('click', function(){
$('#emptydiv').innerHTML = $('#searchbox').value;
}

It copies the value of input into the "emptydiv" div when you click on the button.
Why is the real good question, here, IMO.

I want to create a form for my client. My client require to create a dynamic for him.
Suppose, I want to insert 1 record in main table of mysql, and record multiple records in secondary table which has reference key of main table. I don't know how many records against the main table, it maybe one at time or multiple records at time. I want to do it with single form. If client click add more button it show another text field to insert more data.
how I can do it ?????

It would be possible using pure javascript
like this
<input type="button" onclick="addInput()"/>
<span id="responce"></span>
<script>
var countBox =1;
var boxName = 0;
function addInput()
{
var boxName="textBox"+countBox;
document.getElementById('responce').innerHTML+='<br/><input type="text" id="'+boxName+'" value="'+boxName+'" " /><br/>';
countBox += 1;
}
</script>

This is possible through the jquery/javascript.
So you can use this reference :http://www.mkyong.com/jquery/how-to-add-remove-textbox-dynamically-with-jquery/
Just try it!!

here is the code:
function generateTextBox()
{
var mainDiv=document.getElementById('options');
alert(mainDiv);
var newBreak=document.createElement('br');
mainDiv.appendChild(newBreak);
for(var i=1;i<=4;i++)
{
var newTextBox=document.createElement('input');
var newBreak1=document.createElement('br');
var newBreak2=document.createElement('br');
var newBreak3=document.createElement('br');
var text = document.createTextNode("Option"+i);
newTextBox.type='text';
newTextBox.setAttribute('id','txtAddr'+i);
alert(newTextBox+"2");
mainDiv.appendChild(text);
mainDiv.appendChild(newTextBox);
mainDiv.appendChild(newBreak1);
mainDiv.appendChild(newBreak2);
mainDiv.appendChild(newBreak3);
}
}

This isn't php related, you'll need to dynamically add to the form using javascript.
