我試圖在表單被提交但不作業之前將兩個欄位與我的 javascript 中的結果進行匹配。
如果結果不匹配，我不希望提交表單。
請問有什么解決辦法？謝謝。
代碼如下；
function Check(){
var done=0;
var check=document.check.phone.value;
var check=document.check.pcode.value;
if (phone=="08023" && pcode=="12345") {
alert ("Result Match!");
done=1;
return fasle;
}
if (done==0) {
alert("Result Don't Match!");
}
}<form action=" " method="post">
<input name="phone" maxlength="11" type='tel' id="phone" placeholder="0000-000-0000" required="" />
<br/><br/>
<input name="pcode" maxlength="11" type='tel' id="pcode" placeholder="0000-000-0000" required="" />
<br/><br/>
<button class="button" onClick="javascript:Check()" name="Submit" type="submit" value="Login"><span>Log In </span></button>

您的代碼中有幾個錯誤，我已經為您清理了一些。
function Check() {
var done = 0;
var phone = document.check.phone.value;
var pcode = document.check.pcode.value;
if (phone=="08023" && pcode=="12345") {
alert("Result Match!");
done = 1;
} else {
alert("Result Don't Match!");
}
} <form name="check" action=" " method="post">
<input name="phone" maxlength="11" type='tel' id="phone" placeholder="0000-000-0000" required="" />
<br /><br />
<input name="pcode" maxlength="11" type='tel' id="pcode" placeholder="0000-000-0000" required="" />
<br /><br />
