I am new in Json and javascript . What I want is a select tag with option, thus by selecting the options - that particular object will be fetched from JSON and will be displayed , I have used Nested JSON .
data.json:
var data = {
"abc":{
"color":["rgb(4,45,97)","rgb(255,122,0)"],
"font":"Interface Thin",
"logo":"<img src='logo.png' width='200' height='150'>"
}
}
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="data.json"></script>
</head>
<body>
<!--document.getElementById('color').innerHTML += '<div style="border:1px solid black;padding:2px;width:100px;background-color:'+data.AllenandHanburys[j]+';height:100px"></div>'-->
<p id="demo"></p>
<p id="color"></p>
<p id="logo"></p>
<select id="brand" onChange="run()">
<option>Select Option</option>
<option value="abc">abc</option>
</select>
</body>
<script>
var i;
function run() {
var brand_name=document.getElementById('brand').value;//
for(x in data)
{
if(x==brand_name)
{
for(j in data.brand_name)
{
document.getElementById('demo').innerHTML +=j+":"+data.abc[j]+"<br>";
if(j=='color')
{
for(i=0;i<data.abc.color.length;i++)
{
document.getElementById('color').innerHTML +='<div style="border:1px solid black;padding:2px;width:100px;background-color:'+data.abc.color[i]+';height:100px"></div>'+"<br>";
}
}
}
}
}
}
</script>
</html>
this line is wrong,
for(j in data.brand_name) //because `brand_name` property is not exist in the object
change it to
for(j in data[brand_name]) //data[brand_name] will parsed as data['abc'] which is same as data.abc
Here's the demo
var data = {
"abc":{
"color":["rgb(4,45,97)","rgb(255,122,0)"],
"font":"Interface Thin",
"logo":"<img src='logo.png' width='200' height='150'>"
}
}
var i;
function run() {
var brand_name=document.getElementById('brand').value;//
for(x in data)
{
if(x==brand_name)
{
for(j in data[brand_name])
{
document.getElementById('demo').innerHTML +=j+":"+data.abc[j]+"<br>";
if(j=='color')
{
for(i=0;i<data.abc.color.length;i++)
{
document.getElementById('color').innerHTML +='<div style="border:1px solid black;padding:2px;width:100px;background-color:'+data.abc.color[i]+';height:100px"></div>'+"<br>";
}
}
}
}
}
}
<p id="demo"></p>
<p id="color"></p>
<p id="logo"></p>
<select id="brand" onChange="run()">
<option>Select Option</option>
<option value="abc">abc</option>
</select>

Im sorry if this is a bit of a novice quest. I've only recently started learning. I'm trying to use jQuery to append a series of input text boxes onto my website but nothing I've tried has worked so far.

var levels = 5;
var output = '';
for (var row = 1; row <= levels; row++) {

I have to create table by clicking button where as table contains columns and rows specified by user. After that,we have to fill each table cell by performing onclick with the color listed in the drop down list menu.
The below code snippet is to create table with user's input. I don't know to proceed further. How to perform this ?

Try this : You can add a click event handler for all td and set background-color as a value from dropDown.

You should handle onclick event of td and set background of clicked td to select value

<input type="submit" onclick="searchFor(this.form.searchLoc.value,this.form.searchContent.value);return false;" value="Search"><span class="copyrighttoolbox"> by tool-box.weebly.com</p>
</form>
This is not working and the link after submit became:
http://tool-box.weebly.com/web-tool.html?searchLoc=google&searchContent=search
How can I solve this problem?
Any help will be appreciated.
Try this. It looks like you are mixing up some things as the right value is already in the searchEngine variable.
function searchFor(searchEngine,searchQuery){
if (searchEngine=="google"){
var x="http://google.com.hk/search?q="+searchQuery;
window.location.href=x
}
if (searchEngine=="yahoo"){
var x="http://hk.search.yahoo.com/search?p="+searchQuery;
window.location.href=x
}
if (searchEngine=="bing"){
var x="http://bing.com/search?q="+searchQuery;
window.location.href=x
}
if (searchEngine=="wikipedia"){
var x="http://en.wikipedia.org/w/index.php?search="+searchQuery;
window.location.href=x
}
}
Demo: plunker
Description:
You were cycling through searchEngine instead of just using the value you are passing from the onclick of the submit button.
I also changed this to a switch instead of multiple if statements because of the nature of this use case.
Next i closed all your javascript lines with ; since there were some that were missing it.
Finally I declared the var x at the top of the function so you don't get duplicate variable declaration warnings.
JS
function searchFor(searchEngine,searchQuery){
var x = "";
switch(searchEngine)
{
case "google":
x="http://google.com.hk/search?q="+searchQuery;
alert(x);
window.location.href=x;
break;
case "yahoo":
x="http://hk.search.yahoo.com/search?p="+searchQuery;
window.location.href=x;
break;
case "bing":
x="http://bing.com/search?q="+searchQuery;
window.location.href=x;
break;
case "wikipedia":
x="http://en.wikipedia.org/w/index.php?search="+searchQuery;
window.location.href=x;
break;
}
}

I'm trying to populate 3 drop down exactly the same from each other but select name and option value. I found a simple javascript works fine for my demand; however, unable to make it work once I combo the select list. Below is what I have changed and no longer work correctly when changed. I'm not good with js so any help is appreciated.

I think you can change these lines:
var $vendor+i = $('select.mobile-vendor'+i);
var $model+i = $('select.model'+i);
to
var $vendor = $('select.mobile-vendor'+i);
var $model = $('select.model'+i);
without the need to append the counter to the variable names. inside the function just refer to $vendor and $model
EDIT:
try this code
for (var i=1;i<4;i++) {
var $vendor = $('select.mobile-vendor'+i);
var $model = $('select.model'+i);
$vendor.change(function() {
var $o = $( this );
$o.next().empty().append(function() {
var output = '';
$.each(selectValues[$o.val()], function(key, value) {
output += '<option value='+value+'>' + key + '</option>';
});
return output;
});
}).change();
}
the error is not only how they named their variaves?
var $vendor+i = $('select.mobile-vendor'+i);
would not be so alone?
var $vendor = $('select.mobile-vendor'+i);
