Laravel添加文本框值

Question

是否可以在4.2应用程序中添加（或减去）文本框？

您是否也可以在不刷新页面的情况下创建新的总数？我想添加下面的表单文本来显示最后的余额。

TotalAmountNeeded + TotalRequestFDC + BeforeSixThirty + AfterSixThirty + TotalFromOther =余

{{ 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像这样选择：

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

之后，你要与此元素不管。例如，您可以设置新文字：

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

Answer 2

这将必须在客户/ JavaScript端，而不是在服务器/ Laravel侧完成。使用类似jQuery的东西可以做到这一点。
