问题:

Is it possible to execute copy command using click EVENT?

I have some text selected and I want this text to be copied on onClick event, so that I am able to past this text to another page with out using right click or CTRL+C to copy the text.

回答1:

function copyText(){
    var txt = '';
     if (window.getSelection)
        txt = window.getSelection();
    else if (document.getSelection)
        txt = document.getSelection();
    else return;
    document.getElementById("a").value=txt;
    allCopied =document.getElementById("a").createTextRange();
    allCopied.execCommand("RemoveFormat");

   allCopied.execCommand("Copy");
}

but for security reasons most browsers do not allow to modify the clipboard( except Internet explorer).

HTML

<form name="myForm">
<span onclick="copyText(this)" >Text1</span>, <span onclick="copyText(this)" >Text2</span>

document.myForm.myField.value = element.innerHTML;
}
