我正在创建一个 phonegap 应用程序，我创建了一个带有子页面作为 DIV 的 html5 页面，但是我无法将 javascript 计算值放入我的结果 dash div 中。谁能帮我解决这个问题？？

我想将变量“A”的值放入 div id - timetvA

div id 中的原始变量 - timetvCPTM

$('#timetvCPTM').text(A);

或者

$('#timetvCPTM').append(A);

将 var 打印到 DIV 中

A = $("#timeA").val();
B = $("#timeB").val();
C = $("#timeA").val();
D = $("#timeC").val();
E = $("#timeE").val();

$('#timetvA').append(A);
$('#timetvCPTM').append(raw);

我以前从未使用过 jquery-mobile，但可以尝试一些事情 - 1) 所有脚本都应该放在页面底部，就在正文关闭之前。2）如果您只是要在下一行重新打开它，则不需要关闭脚本标签。3) 这不会影响除整洁之外的任何内容，但您可以定义变量的启动位置（即 var A = document.getElementById('timeA');）。

同样，不确定这些是否有助于解决您的特定问题，但至少可以使您的代码更好。

将以下内容替换为您的timesaving功能

function timesaving(){
var  A  ;
var B ;
var C ;
var D ;
var E ;
A  = document.getElementById('timeA').value;
B = document.getElementById('timeB').value;
C = document.getElementById('timeC').value;
D = document.getElementById('timeD').value;
E = document.getElementById('timeE').value;


var raw = C * (E / 100);
var     loss = (E * raw) / 100;
var     tech = raw + loss;
var     rraw = tech * B;
var     tdum = rraw / C;

Atv = document.getElementById("timetvA")
Atv.innerHTML = A

cptm = document.getElementById("timetvCPTM")
cptm.innerHTML = raw
}
