Bouke的解决办法是可行的。

总的来说,你可能希望这样做,而是一种良好做法:

<input id="my_textbox" onclick="my_textbox_onClick()" />
...
function commonLogic() {
  // Logic that s common to both the onclick event and the *other* code 
}

function my_textbox_onClick() {
  // This function should only contain logic that is triggered by a click on the textbox
  commonLogic();
}

共同点:

doing someting via the inline onclick attribute as you ve got in your example is not the best way. Attaching event handlers in script blocks is better for accessibility and cleaner, maintainable code.
if you re using a library like jQuery already then let the library handle it for you. see code below:

$( #my_textbox ).click(function(){
    //do stuff here
});


//firing the event in some other function
function TriggerTextBoxOnClick(){
    //do stuff here

    $( #my_textbox ).click();

}

你们也可以做与穿便衣成衣的 code一样:

element.onclick = doSomething;
if (element.captureEvents) element.captureEvents(Event.CLICK);
