我有一个
HTML表,其中包含从数据库中提取的记录.从
MySQL数据库中检索“调用时间”列中的条目. “Timer”列中的条目不是从数据库中检索的,而是一个
Javascript计时器.
一旦用户单击确认按钮,计时器Stops和计时器的最终值必须插入数据库.以下Javascript计时器是其他人代码的略微修改版本(Elapsed time from a given time in the database)
问题:我不知道如何将经过时间值插入隐藏表单字段.请注意,每个条目都有一个隐藏的表单字段ID ID =“stoppedtime<?PHP echo $stopid;?>”,我知道我必须继续增加stopid变量的值.我需要插入每个单独的已经过的时间(在按下确认按钮之后)到相应的隐藏表单字段中,以便稍后可以将这些隐藏表单字段中的值插入到数据库中.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> elapsedtimeLogger = function(dateElementId,elapsedElementId,interval) { var container = $(elapsedElementId); var time = parseDate($(dateElementId).text()); var interval = interval; var timer; function parseDate(dateString) { var date = new Date(dateString); return date.getTime(); } function update() { var systemTime = new Date().getTime(); elapsedtime = systemTime - time; container.html(prettyPrintTime(Math.floor(elapsedtime / 1000))); // I KNow I have to do something here to put the elapsed time into the hidden field //But I don't kNow how exactly to do it x = document.getElementById("stoppedid"); // The Problem here is that there are Multiple IDs!! x.value=; prettyPrintTime(Math.floor(elapsedtime / 1000)) // Change the hidden input field value } function prettyPrintTime(numSeconds) { var hours = Math.floor(numSeconds / 3600); var minutes = Math.floor((numSeconds - (hours * 3600)) / 60); var seconds = numSeconds - (hours * 3600) - (minutes * 60); if (hours < 10) hours = "0" + hours; if (minutes < 10) minutes = "0" + minutes; if (seconds < 10) seconds = "0" + seconds; var time = hours + ":" + minutes + ":" + seconds; return time; } this.start = function() { timer = setInterval(function() {update()},interval * 1000); } this.stop = function() { clearTimeout(timer); } } $(document).ready(function () { <?PHP $count= $totalRows; // Total Number of Entries in the Database $datevar=1; $elapsedvar =1; $timeloggervar= 1; $confirmvar=1; if ($count > 0){ do { $count--; $timeloggervar++; $confirmvar++; $datevar++; $elapsedvar++;?> var timeLogger<?PHP echo $timeloggervar; ?> = new elapsedtimeLogger("#date<?PHP echo $datevar; ?>","#elapsed<?PHP echo $elapsedvar; ?>",1); timeLogger<?PHP echo $timeloggervar; ?>.start(); $("#Confirm<?PHP echo $confirmvar; ?>").click(function() { //Stop timer upon clicking the Confirm Button timeLogger<?PHP echo $timeloggervar; ?>.stop(); }); <?PHP } while ($count > 0);}?> }); </script>
一些额外信息:
表中的每个条目都有这样的独特形式.我在表单中放置了一个隐藏字段,以便每个记录的最终ELAPSED TIME VALUE可以存储在值部分中,如下所示.
<?PHP echo'<form action="'.$_SERVER['PHP_SELF'].'" method="post" id="form'.$formid.'">';?> <input name="Num" type="hidden" value="<?PHP echo $results['Time of Call']; ?>" /> **<input type="hidden" name="stoppedtime" id="stoppedtime<?PHP echo $stopid; ?>" value="">** .....
如果你能帮我这个,真的很感激,谢谢!
编辑:
function update(id) { var systemTime = new Date().getTime(); elapsedtime = systemTime - time; container.html(prettyPrintTime(Math.floor(elapsedtime / 1000))); // I KNow I have to do something here to put the elapsed time into the hidden field //But I don't kNow how exactly to do it x = document.getElementById("stoppedid"+id); // The Problem here is that there are Multiple IDs!! x.value= prettyPrintTime(Math.floor(elapsedtime / 1000)); // Change the hidden input field value } this.start = function(id) { timer = setInterval(function(id) {update(id)},interval * 1000); }
解决方法
试试这个,
<script> elapsedtimeLogger = function(dateElementId,hiden,interval) { . . . function update() { var systemTime = new Date().getTime(); elapsedtime = systemTime - time; container.html(prettyPrintTime(Math.floor(elapsedtime / 1000))); $(hiden).val(prettyPrintTime(Math.floor(elapsedtime / 1000))); } . . . $(document).ready(function () { <?PHP for($id=1; $id<$totalRows; $id++){ ?> var timeLogger = new elapsedtimeLogger("#date<?PHP echo $id;?>","#elapsed<?PHP echo $id;?>","#stoppedid<?PHP echo $id;?>",1); timeLogger.start(); $("#Confirm<?PHP echo $id; ?>").click(function() { //Stop timer upon clicking the Confirm Button timeLogger.stop(); }); <?PHP } ?> }); </script>
