表中列的总和

Question

我正在尝试对“已分配的总工作量”和“未呼叫的”列的值求和。

这是我的table HTML

<table border=1 id="category">
    <tr>
        <th>User Name</th>
        <th>User Belongs</th>
        <th>Total Work Assigned</th>
        <th>Not Called</th>
    </tr>
    <tr>
        <td>vidyaranyapura</td>
        <td>Category</td>
        <td>172</td>
        <td>156</td>
    </tr>
    <tr>
        <td>sahasra</td>
        <td>Company</td>
        <td>500</td>
        <td>350</td>
    </tr>
    <tr>
        <td>global</td>
        <td>Not Assigned</td>
        <td>0</td>
        <td>0</td>
    </tr>
</table>

这是片段

 $('#category tr td').text(function(i,el){ console.log(parseInt(el,10)); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table border=1 id="category"> <tr> <th>User Name</th> <th>User Belongs</th> <th>Total Work Assigned</th> <th>Not Called</th> </tr> <tr> <td>vidyaranyapura</td> <td>Category</td> <td>172</td> <td>156</td> </tr> <tr> <td>sahasra</td> <td>Company</td> <td>500</td> <td>350</td> </tr> <tr> <td>global</td> <td>Not Assigned</td> <td>0</td> <td>0</td> </tr> </table> <h3>MY EXPECTED OUTPUT</h3> <table border=1 id="same_id_wont_work_changed_for_demo_only"> <tr> <th>User Name</th> <th>User Belongs</th> <th>Total Work Assigned</th> <th>Not Called</th> </tr> <tr> <td>vidyaranyapura</td> <td>Category</td> <td>172</td> <td>156</td> </tr> <tr> <td>sahasra</td> <td>Company</td> <td>500</td> <td>350</td> </tr> <tr> <td>global</td> <td>Not Assigned</td> <td>0</td> <td>0</td> </tr> <tr> <td></td> <td></td> <td>672</td> <td>506</td> </tr> </table>

Answer 1

我想您想做的是这样的：

演示： https : //jsfiddle.net/zxooa1j4/1/

var sum1 = 0;
var sum2 = 0;
$("#category tr").not(':first').not(':last').each(function() {
  sum1 +=  getnum($(this).find("td:eq(2)").text());
  sum2 +=  getnum($(this).find("td:eq(3)").text());
  function getnum(t){
    if(isNumeric(t)){
        return parseInt(t,10);
    }
    return 0;
    function isNumeric(n) {
        return !isNaN(parseFloat(n)) && isFinite(n);
    }
  }
});
$("#sum1").text(sum1);
$("#sum2").text(sum2);

isNumeric（）函数引自以下答案：

javascript中是否有类似IsNumeric的函数来验证数字

HTML：

<table border=1 id="category">
  <tr>
    <th>User Name</th>
    <th>User Belongs</th>
    <th>Total Work Assigned</th>
    <th>Not Called</th>
  </tr>
  <tr>
    <td>vidyaranyapura</td>
    <td>Category</td>
    <td>172</td>
    <td>156</td>
  </tr>
  <tr>
    <td>sahasra</td>
    <td>Company</td>
    <td>500</td>
    <td>350</td>
  </tr>
  <tr>
    <td>global</td>
    <td>Not Assigned</td>
    <td>0</td>
    <td>0</td>
  </tr>
  <tr>
    <td></td>
    <td></td>
    <td id="sum1"></td>
    <td id="sum2"></td>
  </tr>
</table>

希望这可以帮助。

基于您在拨弄中提供的PHP 。 实际上，当您循环遍历这些值以输出到显示器时，可以总计这些值。

只需替换此foreach部分

$table2 = '<table  id="all_category_data" class="table table-striped table-bordered table-hover"><tr><th>User Name</th><th>User Belongs to</th><th>Total Work Assigned</th><th>Not Called</th><th>Follow Up</th><th>Intrested</th><th>Not Intrested</th></tr>';

foreach($totalresult as $totalresults) {
    $table2 .= "<tr><td>".$totalresults['username'].
    "</td><td>".$totalresults['userbelongs'].
    "</td><td>".$totalresults['totalvalue'].
    "</td><td>".$totalresults['Notcalled'].
    "</td><td>".$totalresults['followUp'].
    "</td><td>".$totalresults['intrested'].
    "</td><td>".$totalresults['notIntrested'].
    "</td></tr>";
}

$table2. = '</table>';

echo $table2;

以下内容包括加法和输出

$table2 = '<table  id="all_category_data" class="table table-striped table-bordered table-hover"><tr><th>User Name</th><th>User Belongs to</th><th>Total Work Assigned</th><th>Not Called</th><th>Follow Up</th><th>Intrested</th><th>Not Intrested</th></tr>';
$totalValue = 0;
$notCalledValue = 0;
foreach($totalresult as $totalresults) {
    // addition of totalValue
    $totalValue = $totalValue + $totalresults['totalvalue'];
    // addition of notCalledValue
    $notCalledValue = $notCalledValue + $totalresults['Notcalled'];

    $table2 .= "<tr><td>".$totalresults['username'].
    "</td><td>".$totalresults['userbelongs'].
    "</td><td>".$totalresults['totalvalue'].
    "</td><td>".$totalresults['Notcalled'].
    "</td><td>".$totalresults['followUp'].
    "</td><td>".$totalresults['intrested'].
    "</td><td>".$totalresults['notIntrested'].
    "</td></tr>";
}
// output of totalValue and notCalledValue
$table2 .= "<tr><td>".
    "</td><td>".
    "</td><td>".$totalValue.
    "</td><td>".$notCalledValue.
    "</td><td>".
    "</td><td>".
    "</td><td>".
    "</td></tr>";

$table2. = '</table>';
echo $table2;

注意 ：这假定您数据中的$totalresults['totalvalue']和$totalresults['Notcalled']键是数字。
