Question

我是一名平面设计师而非程序员但我按照一些教程为在线表格网页制作了佣金

我想知道如何计算此表中的价格（分销商的总数和公众的第二总数）＆gt;。＆gt;我知道这很复杂。

我试图将cwolves答案添加到代码页中..但它与我的提交按钮冲突..如果没有按钮，它会自动出现..出现在表格下方的某处？

呃，为什么不呢。使用jQuery：

eval( $( 'td:nth-child(3)' ).map( function( td, $this ){
    return ( ( parseFloat( ( $this = $( this ) ).text() ) || 0 )
        * ( parseFloat( $this.parent().find( 'select' ).val() ) || 0 ) );
} ).get().join( '+' ) )

将nth-child(3)更改为4以获取公共价格

（对于任何想批评我的人来说，这与问题本身的质量相同）
