【问题描述】:
我昨天问了一个问题,这让我走上了正确的道路,但我又完全陷入了困境。
大纲:
我有 3 张桌子;
表 1 - 预期数据 (#expected)
表 2 - 预期的确认数据 (#scannedExp)
表 3 - 意外确认数据 (#scannedUnExp)
举个例子..
如果我要在输入框中输入“6666”
它将“#expected”表中的数量减少 1,但在“#scannedExp”表中创建一个数量为 1 的列(即 desc,从 #expected 表中抓取的笼子)。
如果我们这次输入'6666',它将删除“#expected”行,但增加表“#scannedExp”
如果这次我们再次输入“6666”,它将在“#scannedUnExp”中添加一行,仅包含代码和数量(不需要 desc 或笼子)
如果我们输入“1234”,它会在“#scannedUnExp”中添加一行
由于某种原因,我的代码无法在 Jsfiddle 中运行,因为它在某种程度上可以在我的浏览器中运行。
<body>
<input type="text" style="width: 200px" id="code" name="code" />
<input id = "btnSubmit" type="submit" value="Submit"/>
<P>Scanned Expected</P>
<table id = "scannedExp" > <thead>
<tr>
<th>Code</th>
<th>Desc</th>
<th>Qty</th>
<th>Cage</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<P>Scanned Un Expected</P>
<table id = "scannedUnExp" > <thead>
<tr>
<th>Code</th>
<th>Qty</th>
<th>Cage</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<P>Data Expected</P>
<table id = "expected"> <thead>
<tr>
<th>Code</th>
<th>Desc</th>
<th>Qty</th>
<th>Cage</th>
</tr>
</thead>
<tbody>
<tr id="4444" >
<td>4444</td>
<th>Car Door</th>
<td>3</td>
<th>S2222</th>
</tr>
<tr id="5555" >
<td>5555</td>
<th>door handel</th>
<td>1</td>
<th>S2222</th>
</tr>
<tr id="6666" >
<td>6666</td>
<th>headlight</th>
<td>2</td>
<th>S2222</th>
</tr>
<tr id="7777">
<td>7777</td>
<th>seat</th>
<td>5</td>
<th>S2222</th>
</tr>
</tbody>
</table>
</body>
我的 javascript
$(window).load(function(){
$("#btnSubmit").on("click", function(){
numRows = $("#expected tr").length; //loop thought expected data
for(var i=1 ; i<numRows ; i++){
var code = $("#expected tr:nth-child(" + i + ") td:nth-child(1)").html();
var desc = $("#expected tr:nth-child(" + i + ") td:nth-child(2)").html();
var qty = $("#expected tr:nth-child(" + i + ") td:nth-child(3)").html();
var cage = $("#expected tr:nth-child(" + i + ") td:nth-child(4)").html();
// if code is in expected data -1 from qty col
if(code == $("#code").val()){
$("#expected tr:nth-child(" + i + ") td:nth-child(3)").html(parseInt(qty) - 1);
//delete if last one in expected table
if(qty ==1 ){$("#" + code).remove();}
// loop thought scanned expected table
numRowsB = $("#scannedExp tr").length;
for(var ib=1 ; ib<numRows ; ib++){
var codeExp = $("#scannedExp tr:nth-child(" + ib + ") td:nth-child(1)").html();
var qtyExp = $("#scannedExp tr:nth-child(" + ib + ") td:nth-child(3)").html();
// if in scannedExp add qty by one
if(codeExp == $("#code").val()){
$("#scannedExp tr:nth-child(" + ib + ") td:nth-child(3)").html(parseInt(qtyExp) + 1);
return true;
}
else{ //if not found in expected table add row to scannedExp
$("#scannedExp tbody").append("<tr><td>" + $("#code").val() + "</td><td>" + desc + "</td><td>1</td><td>" + cage + "</td></tr>");
return true;
}
}
return true;
}
else{
alert("not in expected");
}
}})
});
