Laravel添加文本框值

Question

是否可以在4.2應用程序中添加（或減去）文本框？

您是否也可以在不刷新頁面的情況下創建新的總數？我想添加下面的表單文本來顯示最後的餘額。

TotalAmountNeeded + TotalRequestFDC + BeforeSixThirty + AfterSixThirty + TotalFromOther =餘

{{ HTML::row() }} 
{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('TotalAmountNeeded', 'Total Amount Needed') }} 
{{ Form::text('TotalAmountNeeded', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 

{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('TotalRequestFDC', 'Total Requested from FDC') }} 
{{ Form::text('TotalRequestFDC', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 


{{ HTML::row() }} 
{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('BeforeSixThirty', 'Amount Before 6/30') }} 
{{ Form::text('BeforeSixThirty', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 

{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('AfterSixThirty', 'Amount After 6/30') }} 
{{ Form::text('AfterSixThirty', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 
{{ HTML::closeRow() }} 
{{ HTML::row() }} 
{{ HTML::closeCol() }} 
{{ HTML::closeRow() }} 

{{ HTML::row() }} 

{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('TotalFromOther', 'Total From Other') }} 
{{ Form::text('TotalFromOther', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 

{{ HTML::col(6,6,6,6) }} 
{{ Form::formGroup() }} 
{{ Form::label('Remainder', 'Remainder Balance') }} 
{{ Form::text('Remainder', '0', ['class' => 'form-control', 'data-fv-notempty' => 'false']) }} 
{{ Form::closeFormGroup() }} 
{{ HTML::closeCol() }} 
{{ HTML::closeRow() }} 

Answer 1

您可以使用jQuery像這樣選擇：

$("[name='TotalAmountNeeded']"); 

之後，你要與此元素不管。例如，您可以設置新文字：

$("[name='TotalAmountNeeded']").val('New text'); 

Answer 2

這將必須在客戶/ JavaScript端，而不是在服務器/ Laravel側完成。使用類似jQuery的東西可以做到這一點。
