我有一个 php 表单和一个名为 countdown.js 的单独 javascript 文件，该文件将计时器运行到目标日期，然后显示一条消息，我尝试了各种方法来让提交按钮在完成后禁用。

这是我的表格

<form id="MakeBid" action="MakeBid.php" method="POST">
<input type="hidden" name="propertyID" value ="1"/>
<div>Bid Now <input type="text" name="pricesoldfor"/></div> 
<input id = "submit" input type="submit" value="Submit" /> 
</form>

这是我的java代码

function calcage(secs, num1, num2) {
    s = ((Math.floor(secs / num1)) % num2).toString();
    if (LeadingZero && s.length < 2) s = "0" + s;
    return "<b>" + s + "</b>";
}

function CountBack(secs) {
    if (secs < 0) {
        document.getElementById("cntdwn").innerHTML = FinishMessage;


        return;
    }
    DisplayStr = DisplayFormat.replace(/%%D%%/g, calcage(secs, 86400, 100000));
    DisplayStr = DisplayStr.replace(/%%H%%/g, calcage(secs, 3600, 24));
    DisplayStr = DisplayStr.replace(/%%M%%/g, calcage(secs, 60, 60));
    DisplayStr = DisplayStr.replace(/%%S%%/g, calcage(secs, 1, 60));
    document.getElementById("cntdwn").innerHTML = DisplayStr;
    if (CountActive) setTimeout("CountBack(" + (secs + CountStepper) + ")", SetTimeOutPeriod);
}

function putspan(backcolor, forecolor) {
    document.write("<span id='cntdwn' style='background-color:" + backcolor + "; color:" + forecolor + "'></span>");
}

if (typeof(BackColor) == "undefined") BackColor = "white";
if (typeof(ForeColor) == "undefined") ForeColor = "black";
if (typeof(TargetDate) == "undefined") TargetDate = "12/31/2020 5:00 AM";
if (typeof(DisplayFormat) == "undefined") DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
if (typeof(CountActive) == "undefined") CountActive = true;
if (typeof(FinishMessage) == "undefined") FinishMessage = "";
if (typeof(CountStepper) != "number") CountStepper = -1;
if (typeof(LeadingZero) == "undefined") LeadingZero = true;
CountStepper = Math.ceil(CountStepper);
if (CountStepper == 0) CountActive = false;
var SetTimeOutPeriod = (Math.abs(CountStepper) - 1) * 1000 + 990;
putspan(BackColor, ForeColor);
var dthen = new Date(TargetDate);
var dnow = new Date();
if (CountStepper > 0) ddiff = new Date(dnow - dthen);
else ddiff = new Date(dthen - dnow);
gsecs = Math.floor(ddiff.valueOf() / 1000);
CountBack(gsecs);​

我假设您的计时器运行良好并且消息显示正确。

你尝试过使用 jQuery 吗？要禁用提交按钮，只需插入以下行：

$("input[type=submit]").attr("disabled", "disabled");

这是你想要达到的目标吗？

同样在下面我粘贴了您解决类似问题的链接：

jQuery禁用/启用提交按钮

编辑：

根据您的代码（并假设它正在工作），请执行以下操作：

  • 将 jQuery 添加到您的站点：http: //jquery.com/
  • 修改你的 CountBack 函数，添加我document.getElementById("cntdwn").innerHTML = FinishMessage;之前和之后提供的代码return;

应该管用！
