jQuery Click事件触发，无需单击

Question

I am facing a tricky problem with my code and hope to get some help on this. Below is a snippet of my code:

<SCRIPT type='text/javascript'>

function list(json) {
// list result
$('#pop-up').click(alert(json.length));
}

// declare map and options

google.maps.event.addListener(map, 'idle', function () {
var query = 'some query';
$.getJSON(query, list); 
});

</SCRIPT>
<A href='javascript:void(0)' id='pop-up'>Click Me</A>

As seen, the pop-up is supposed to return the length of json object when the pop-up link is clicked. However, I am getting the pop-up without clicking the link. Anyone knows where the problem lies?

Answer 1

It's because you're using .click() rather than .click(function() {}) . Replace the $('#pop-up') line with:

$('#pop-up').click(function() { alert(json.length) });

and get rid of the curly brace underneath that line.
