js realizes the effect of pressing Ctrl Enter to send_javascript skills

1. Listen to the onkeydown event of textarea

Copy code The code is as follows:

8db83ab39dd4eb6d2c77abf33d4c317940587128eee8df8f03d0b607fe983014

2. Send the form and then reload the opener window (see 4,)

function sbFrm() {
var Contenthf=document.getElementById("Contenthf");
var txtAr = Contenthf.getElementsByTagName("textarea")[0];
if (txtAr.innerHTML == "") {
txtAr.focus();
return false;
}
Contenthf.submit();
window.opener.afterReload();
return false;
}

3. When the ctrl key is pressed and the keycode is 13 (Enter), the function that sends the form is called.

function keySend(event) {
if (event.ctrlKey && event.keyCode == 13) {
sbFrm();
}
}

4. If it is the current page opened by window.open(), add a reload function to the page of window.open

function afterReload() {
setTimeout(function () {
window.location.reload();
}, 1000);
}
