所以,我有一个带有两个滑块的网页,用于设置数值和四个单选按钮,用于选择计算操作和“计算”按钮。如何检测滑条值和选择哪个操作,然后相应地计算这些值并将它们输出到“计算”按钮的标签上?注意:我对javascript/jquery完全新鲜。使用JQuery进行计算/ javascript

在你的滑块中你正在做'min:1,max:1000,value:0,';即您将初始_value_设置为低于_minimum_。此外,这看起来不像有效的HTML - 多个“”元素,“”元素和“<!doctype ..”。您还多次包含脚本。这是多页还是只有一页? – 2013-03-17 22:07:01

它只有1页。 – cvenko 2013-03-17 22:15:46

这就是这个页面的样子:http://shrani.si/f/3L/3i/36jR3xsi/sample.png – cvenko 2013-03-17 22:19:52

我知道很多人说,你应该在你的HTML工作。我也这么认为,但是我在学习时学到了很多看例子(javascript或者php)。所以我决定告诉你如何做到这一点。当然,你会从中学习,或者复制它并使用。随你便。我只希望你会尝试去理解它。

$("button").button().click(function (event) { 
    event.preventDefault(); 
    var value1 = parseInt($("#amount").val()); //get value of first slider 
    var value2 = parseInt($("#amount2").val()); //value of second slider 
    var result = 0; 
    var radioval = $('input[name=radio]:checked', '#myForm').val(); //get value of the radio bytton 

    //calculations depending of chose of the radio button 
    if (radioval == "Addition") result = value1 + value2; 
    else if (radioval == "Substraction") result = value1 - value2; 
    else if (radioval == "Multiplication") result = value1 * value2; 
    else if (radioval == "Division") result = value1/value2; 

    $("#resultlabel").text("Result: " + result); //show result 
}); 

整个代码,有一些修正(我删除了里面的div头/ HTML/body标签),你可以在这里找到:http://jsfiddle.net/k9rGx/9/

记住,你只需要一次链接的.js和.css文件,在<head></head>标签,在网站顶部。你不需要每次使用javascript都做。它适用于整个网站。

我只希望它能帮助你学习新东西。
