Help in calling a javascript function from php or html

This might be simple to someone, but I am a bit of a novice and searched everywhere. I have a javascript function.

mkfile : function(fm) {

I am trying to execute this from an on click comm开发者_开发知识库and.

Any ideas. Sorry Im a bit of a dunce in this, but I have tried everything and nothing happens.


Use the attribute onclick as follows: <a onclick="javascript:mkfile()" >Bob</a>. You don't have to have the javascript: before-hand but it helps in browsers like IE (don't even get me started).

By the way, your code is wrong, it should be

function mkfile(fm) {
  // your code
}

Don't hesistate to ask if you don't understand this.


Without more code it is difficult to tell what you are doing wrong, but normally it goes like this:

<button id="foo">Click me!</button>

<script type="text/javascript">

    document.getElementById('foo').onclick = function() {
        alert('Hello World!');
    }

</script>

There are several ways of binding event handlers. I suggest to read quirksmode.org - Introduction to Events , MDC - Event handlers and MDC - The DOM and JavaScript and also follow the links given there ;)


As others have noted, it's not really possible to see what is wrong with your code without seeing more of it. But the small portion you posted (with its name:value) is valid only in a couple of circumstances, both of which are somewhat common patterns of JS design:

// Pattern one
var makeMyObject = function() {
    var privateVar = 'a private member';
    var privateMethod = function() {};
    var objOut = {
        mkDir:function() {/*more code*/},
        mkFile:function() {/*more code*/},
        delFile:function() {/*more code*/}
    };
    return objOut;
};
myObject = makeMyObject();
myObject.mkFile();

// Pattern two
var myObject = {
    mkDir:function() {/*more code*/},
    mkFile:function() {/*more code*/},
    delFile:function() {/*more code*/}
};
myObject.mkFile();

If this is what you have, the way you can bind this to an onclick in your HTML code is:

<a href="/some_page.html" onclick="myObject.mkFile()">Click here</a>

Or in your JS,

domMyAnchorElement.onclick = myObject.mkFile; // Note there are no parens because you are binding the function, not invoking it.
