Is it possible to write the code below in a single line?
<a href="#" onClick="function(){ //do something; return false;};return false;"></a>
As an alternative to:
<a href="#" onClick="doSomething(); return false;"></a>
function doSomething(){
//do something;
}
If you want to trigger an alert message using Self-Executing Anonymous Functions, you can implement the following code:
<button onClick="(function(){
alert('Hello! I am triggered');
return false;
})();return false;">Click here</button>Try this method:
<a href="#" onclick="function greet(){alert('Hello!')};greet()">click</a>
You have the option to embed JavaScript directly within the onclick attribute, similar to how you would assign a method in JavaScript code. It's important to maintain clean and organized code by containing your JavaScript within a script block.
After reviewing the response provided by @Mukund Kumar, a revised version has been created that includes passing the event argument to the anonymous function:
<a href="#" onClick="(function(e){
console.log(e);
alert('I initiated the call');
return false;
})(arguments[0]);return false;">click here</a>
While not typically advised, you have the option to execute everything inline as shown below:
<a href="#" onClick="function example(){ /* Perform an action */ } example(); return false;"></a>
It's hard for me to identify a scenario where this approach would be superior to organizing the function elsewhere and calling it using onClick.
While this thread may be old, I recently came across the same issue and found a solution that works perfectly without any console errors or warnings. When you're "inlining" JavaScript code like the example below, there's no need to include "function xx()". Take a look at the following snippet:
Here's a simple solution I wanted to share:
<a href="#" type="button" onClick="var myDiv = document.getElementById('myDIV'); if (myDiv.style.display === 'block') { myDiv.style.display = 'none'; } else { myDiv.style.display = 'block'; }">click</a>
In a standard HTML setup, the same functionality can be achieved with the following implementation of inlined JavaScript:
<body>
<a href="#" type="button" onclick="myFunction()">Try it</a>
...(the rest of the HTML content)....
<script>
function myFunction() {
var x = document.getElementById("myDIV");
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
}
</script>
</body>
