The Javascript onclick function is a popular part of Javascript. The Javascript onclick function makes it easy and simple for one to quickly link a page.
There are events that are associated with form elements. Say suppose there is a button in form. One could associate an event to it say onclick event. Now when the button is clicked, the onclick event is called or in other words onclick event is fired.From javascript code side it can be said that it only gets called on fireevent of button script
we can do this using of javascript. you can use this following code: <input type=button value="button" onClick=onclick_function()> here onclick_function() is a function which is called by javascript on clicking the button. javascript code is as follows: <script language="javascript" type="text/javascript"> // your code for onclick_function() function onclick_function(){ alert("Welcome to javascript"); } </script>
You have to use JavaScript. It is built into the DOM, but it requires that to read and manipulate the Document Object Model.
To create a button that displays text after being clicked, you can use HTML and JavaScript. Here's an example code: HTML: <button onclick="displayText()">Submit</button> <p id="text"></p> JavaScript: function displayText() { document.getElementById("text").innerHTML = "Text to display after clicking submit button."; } In this code, the button is created using the <button> tag and an onclick attribute is added to call the displayText() function when clicked. The function displayText() uses JavaScript to access the element with the ID "text" and change its innerHTML to the desired text, which will be displayed below the button.
Dynamic HTML is basically using HTML and some other things to enhance it, usually Javascript and Styles. All HTML really does is format your page. To get your page to do things, you need more than just plain HTML. The following code will create a button that you can click on and it will pop up a message. It uses Javascript. Copy and paste it or type it exactly as it is into your code and it will work.The onClick="alert('Hello');" piece is Javascript. Without it you would still have the button, but when it was clicked, it would not do anything. The Javascript makes your page come alive as it were. That is the idea of Dynamic HTML.
<table> <th onclick="checkData()">ID</th> <th onclick="checkData()">Name</th> </table> <script type="text/javascript" language="javascript"> function checkData() { // Your Javascript code here alert("It Works"); } </script>
Whatever method is attached to the event, is executed.
function blahblah () { //do something } blahblah();

No. PHP runs on the server. It receives a http request from the web server, and sends output (typically as html) to the browser. Any code in an onclick event would be handled by javascript. To send data back to the webserver (and PHP) you can make a synchronous request (AJAX) from an onclick, or any other browser event.
That depends. If you just put some javascript code somewhere (like document.write('hello')) it will be executed on page load. However, you'll mostly want to use functions; you then call those functions on certain events (like a button onclick) to execute their code.
They are typically "A" elements in HTML. They can also be "onclick" events, running something like javascript that performs a window.open action.
To create a button that displays text after being clicked, you can use HTML and JavaScript. Here's an example code: HTML: <button onclick="displayText()">Submit</button> <p id="text"></p> JavaScript: function displayText() { document.getElementById("text").innerHTML = "Text to display after clicking submit button."; } In this code, the button is created using the <button> tag and an onclick attribute is added to call the displayText() function when clicked. The function displayText() uses JavaScript to access the element with the ID "text" and change its innerHTML to the desired text, which will be displayed below the button.
Apply an onclick event handler to the image. For example: <img src="myimage.png" onclick="enableFormField();" /> Then, you can write the function enableForm like this: function enableFormField() { var theInput=document.getElementById("myFormField"); //Modify the line of code above so that theInput refers to the form field //you want to enable. theInput.disabled=false; }
