jquery - 添加隐藏字段，包括当前提交字段值并作为隐藏字段发送到下一页

Question

此表单实际上正在获取一些输入字段，如下所示。

我需要添加输入(隐藏)字段值和我从 custom12 获取的值，并在隐藏字段中作为自定义 13 发送到下一页。如何做到这一点

Answer 1

您可以使用 localstorage或 Cookies使用 javascript 将数据从一个页面发送到另一个页面。

喜欢，

$'#submitDetails').on('click',function(){
    localStorage.setItem('formData',$('#submitDetails').serialize());
    $('#submitDetails').submit();
    // set form data to local storage
});

阅读serialize()

或者，你可以试试这个，

首先更改表单的id，因为id必须唯一 并且您的 button 和 form 都具有相同的 id。

$( "#submitDetails" ).on('click',function( event ) {    
    var c4 = parseInt($('input[name="custom4"]').val());
    var c5 = parseInt($('input[name="custom5"]').val());
    var c6 = parseInt($('input[name="custom6"]').val());
    var c7 = parseInt($('input[name="custom7"]').val());
    var c8 = parseInt($('input[name="custom8"]').val());
    var c9 = parseInt($('input[name="custom9"]').val());
    var c10 = parseInt($('input[name="custom10"]').val());
    var c11 = parseInt($('input[name="custom11"]').val());    
    var radioVal= parseInt($('input[name="custom12"]:checked').val());    
    var total = c4 + c5 + c6 + c7 + c8 + c9 + c10 + c11 + radioVal;    
    $('#custom13').val(total);// send this value to next form    
});
