當textarea不爲空時，表單應該被提交（$ PHP_SELF），這樣我就可以得到textarea的值。但是在提交之前，會出現一個對話框。當用戶點擊是時，他將被重定向到不同的頁面。我的問題是我不知道在哪裏放置返回'真'，以便頁面將被提交以便我獲得textarea的價值。我把這個返回'假'在這裏：Javascript，jQuery，PHP問題。
if(form.rules.value=='')
{
printToPage('output','Please enter the rules.','text')
hello();
return false;
}
當textarea爲空，表單將不會提交，並會出現一個不同的對話框。我應該在什麼地方將返回值設置爲「真」，以便只有在用戶在textarea中輸入內容並點擊「是」之後纔會提交頁面。
我已經發布了代碼，我試圖在返回'真正'沒有成功。
