Question

我有以下代码：

for(i=0;i<data.length;i++){
    // alert(data[i].stock_id);
    html1 += '<tr>\n\
            <td><input type="text" style="width:80px !important;" readonly id="patient_name' + i + '" name="patient_name[]" value="'+data[i].patient_name+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="description' + i + '" name="description[]" value="'+data[i].description+'"/></td>\n\\n\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="amount' + i + '" name="amount[]" value="'+data[i].amount+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="qauntity' + i + '" name="quantity[]" value="'+data[i].quantity+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="charged'+i+'" name="charged[]" value="'+data[i].charged+'"></td> \n\
            <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_visit_statement_id'+i+'" name="patient_visit_statement_id[]" value="'+data[i].patient_visit_statement_id+'"></td> \n\
            <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_payment_id[]" value="'+data[i].patient_payment_id+'"></td> \n\\n\
            <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_id[]" value="'+data[i].patient_id+'"></td> \n\
            <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="visit_id'+i+'" name="visit_id[]" value="'+data[i].visit_id+'"></td> \n\n\
    </tr> ';

} 
htmlhead1+='\n\
    <th style="width:80px !important;" >Patient Name</th>\n\
    <th style="width:80px !important;" >  Description</th> \n\
    <th style="width:80px !important;" > Amount </th> \n\
    <th style="width:80px !important;" >Quantity</th> \n\
    <th style="width:80px !important;" >Charged? </th> \n \n \n';

$('#tbody1').empty();
$('#tbody1').append(htmlhead1);
$('#tbody1').append(html1);
$('#tbody1').append(total_price);

for循环表单填充数据库中值的表中的动态列表，我想将金额的值相加并将其视为总金额/价格。如何计算循环中的总量并将其附加到＃tbody1？

Answer 1

试试这个

var amountTotal = 0;
    for(i=0;i<data.length;i++){
        amountTotal += data[i].amount;
        // alert(data[i].stock_id);
        html1 += '<tr>\n\
                <td><input type="text" style="width:80px !important;" readonly id="patient_name' + i + '" name="patient_name[]" value="'+data[i].patient_name+'"/></td>\n\
                <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="description' + i + '" name="description[]" value="'+data[i].description+'"/></td>\n\\n\n\
                <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="amount' + i + '" name="amount[]" value="'+data[i].amount+'"/></td>\n\
                <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="qauntity' + i + '" name="quantity[]" value="'+data[i].quantity+'"/></td>\n\
                <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="charged'+i+'" name="charged[]" value="'+data[i].charged+'"></td> \n\
                <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_visit_statement_id'+i+'" name="patient_visit_statement_id[]" value="'+data[i].patient_visit_statement_id+'"></td> \n\
                <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_payment_id[]" value="'+data[i].patient_payment_id+'"></td> \n\\n\
                <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_id[]" value="'+data[i].patient_id+'"></td> \n\
                <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="visit_id'+i+'" name="visit_id[]" value="'+data[i].visit_id+'"></td> \n\n\
        </tr> ';

    }

最后通过附加在htmlhead1

中使用amountTotal打印金额

Answer 2

您可以在某处添加各个值。在它上面，你只需要添加你所拥有的循环，只有添加。

在你的周期之前

   var total_amount=0;
   var total_quantity=0;

然后添加到它

total_amount+=data[i].amount;
total_quantity+=data[i].quantity;

然后你只需要编译TOTAL_PRICE并插入这些变量

Answer 3

实施例

var myData = [1,2,3];

var myTotal = 0;  //Variable to hold your total

for(var i=0, len=myData.length; i<len; i++){
    myTotal += myData[i];  
}

alert(myTotal); // 6

Answer 4

试用此代码： -

var total=0;
for(i=0;i<data.length;i++){
    total+=data[i].amount;
    html1 += '<tr>\n\
            <td><input type="text" style="width:80px !important;" readonly id="patient_name' + i + '" name="patient_name[]" value="'+data[i].patient_name+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="description' + i + '" name="description[]" value="'+data[i].description+'"/></td>\n\\n\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="amount' + i + '" name="amount[]" value="'+data[i].amount+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="qauntity' + i + '" name="quantity[]" value="'+data[i].quantity+'"/></td>\n\
            <td><input type="text" style="width:80px !important;" readonly class="SmallInput" id="charged'+i+'" name="charged[]" value="'+data[i].charged+'"></td> \n\
            <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_visit_statement_id'+i+'" name="patient_visit_statement_id[]" value="'+data[i].patient_visit_statement_id+'"></td> \n\
            <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_payment_id[]" value="'+data[i].patient_payment_id+'"></td> \n\\n\
            <td><input type="hidden" style="width:80px !important;" readonly class="SmallInput" id="patient_id'+i+'" name="patient_id[]" value="'+data[i].patient_id+'"></td> \n\
            <td><input type="hidden" style="width:80px color:red!important ;" readonly class="SmallInput" id="visit_id'+i+'" name="visit_id[]" value="'+data[i].visit_id+'"></td> \n\n\
    </tr> ';

} 
html1 += '<tr>\n\
      <td>
        <input type="text" id="total_ans">    
      </td>  
</tr>';


var textBox = document.getElementById("total_ans");
textBox.value = total.toString();;

通过此代码，您可以获得总答案并在tbody中附加答案。
