I have a javascript from textarea:
<textarea id="result">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript" src="widget.js"></script>
<script type="text/javascript" src="test.php"></script>
</textarea>
I want to get html from this javascript:
<script>
$(document).ready(function(){
$(".submit").click(function(){
var html = $('#result').val();
$('#content').html(html);
});
});
</script>
<input type="button" class="submit" value="Ok" />
<div id="content"></div>
Result output is an error. How do I do this?
use var html = $('#result').html();

<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.3.1.min.js
"></script>
<script type="text/javascript">
$(function(){
for(i=0;i<5;i++){
var ids=[1,2,3,4,5];
$("#btn"+ids[i]).click(function(){
alert("btn"+ids[i]);
});
}
});
</script>
</head>
<body>
<button id="btn1">按钮1</button>
<button id="btn2">按钮2</button>
<button id="btn3">按钮3</button>
<button id="btn4">按钮4</button>
<button id="btn5">按钮5</button>
</body>
</html>
Clicking the button should alert the value in the array, but it instead alerts btnundefine.
How can I visit the value in the external array in the lambda function?
Define i with let. Otherwise, it will try to access ids[5] and prints undefined because ids array only has 5 elements.
$(function(){
var ids=[1,2,3,4,5];
for(let i=0;i<5;i++){
$("#btn"+ids[i]).click(function(){
alert("btn"+ids[i]);
});
}
});
<script typetype=="text/javascript" src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<button id="btn1">按钮1</button>
<button id="btn2">按钮2</button>
<button id="btn3">按钮3</button>
<button id="btn4">按钮4</button>
<button id="btn5">按钮5</button>
This is workable also:
<html>
<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.3.1.min.js
"></script>
<script type="text/javascript">
$(function(){
var ids=[1,2,3,4,5];
for(i=0;i<5;i++){
console.log("#btn"+ids[i]);
$("#btn"+ids[i]).click(function(){
alert(this.id);
});
}
});
</script>
</head>
<body>
<button id="btn1">按钮1</button>
<button id="btn2">按钮2</button>
<button id="btn3">按钮3</button>
<button id="btn4">按钮4</button>
<button id="btn5">按钮5</button>
</body>
</html>
I am trying to use ajax but it is not working when I clicks the button it does not show the alert box on browser.
<html>
<head>
<title>Ajax</title>
<script scr="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
Name: <input type="text" id="data">
<input type="submit" id="sub" value="save">
<script>
$(document).ready(function () {
$('#sub').click(function () {
alert('ok');
});
});
</script>
</body>
</html>
Please try the below code
<html>
<head>
<title>Ajax</title>
<script src="https://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
$(document).ready(function(){

1. problem with the jquery path
2. always put the scripts in the head section
I have two html pages named order.html,check.html and test.js(included in both html files)
When i click on submit button in order.html,amount field value from order.html should get updated/populate into cost field of check.html.
Below is the code i am using but its not working,can someone let me know whats wrong??
order.html
<html>
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<form name="order" action="check.html" method="get">
name:<input type ="text" id="amount" name="amount">
<input type="submit" value="finish" onclick="cost()" >
</form>
</body>
</html>
check.html
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<form name="check" action="confirm.html" method="get">
<input type="text" name="cost" id="cost" readonly="readonly">
</form>
</body>
</html>
test.js
function cost(){
var amount= $("#amount").val();
jQuery.load("check.html",function(){
$("#cost").html(amount);
});
}
Your order.html input type submit should be input type button.
Change your test.js to
function cost(){
var amount= $("#amount").val();
$('body').load("check.html",function(){
$("#cost").val(amount);
});
}
And input type="button"
Try this:
order.html:
<html>
<head>
<script language="javascript" type="text/javascript" src="test.js"></script>
</head>
<body>
<div id="main_div">
<form name="order" action="check.html" method="get">
name:<input type="text" id="amount" name="amount"> <input
type="button" value="finish" id="submit_btn">
</form>
</div>
</body>
</html>
Jquery:
$(document).ready(function() {
$('#submit_btn').click(function() {
var amount = $("#amount").val();
$('#main_div').load("check.html", function() {
$('#main_div').find("#cost").val(amount);
});
});
});
<body>
<script type="text/javascript">
var a="sreedhar";
<input type="text" value="abc">
</script>
</body>
It gives the syntax error.
can't we use "html tags" directly in "javascript".
No, you can't use them directly in JavaScript.
However you may treat them as strings:
var str = '<input type="text" value="abc">';
or as DOM elements:
var input = document.createElement('input');
input.type = 'text';
input.value = 'abc';
And then append to the markup, e.g. document.body.appendChild(input);.
Usually a well formated hmtl with javascript looks like this.
<HTML>
<HEAD>
<script type="text/javascript">
var a="sreedhar";
</script>
</HEAD>
<BODY>
<input type="text" value="abc">
</BODY>
</HTML>
If you want to generate some html with javascript then assign it as a string to some variable.
For example you have a div having id='abc' and you want to generate a textbox in this div then you need to do like this
<script type="text/javascript">
var textbox = '<input type="text" value="abc">';
$('#abc').append(textbox);
</script>
Maybe you want this:
<script type="text/javascript">
var a="sreedhar";
document.write('<input type="text" value="abc">');
</script>
</BODY>
<html>
<head>
<title> New Document </title>
<script type="text/javascript">
//put javascript function here
</script>
</head>
<body>
<input type="text" value="abc">
</body>
</html>
You can use html element inside the javascript using element id.
Here is a simple code which takes input and print it on the same page. But it is not working when I click on button. Please help regarding this.
<html>
<head>
<script>
function changeHTML() {
$("#withjQuery").html($("#theInput").val());
}
</script>
<body>
<input type='text' id='theInput' value='Write here' />
<input type='button' onClick='changeHTML();' value='See what you wrote with jQuery.html'/>
<div id="withjQuery"></div>
</body>
</head>
You do not have jQuery library included in the page
Add
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
ex
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script>
function changeHTML() {
$("#withjQuery").html($("#theInput").val());
}
</script>
</head>
<body>
<input type='text' id='theInput' value='Write here' />
<input type='button' onClick='changeHTML();' value='See what you wrote with jQuery.html'/>
<div id="withjQuery"></div>
</body>
</html>
