jQuery实现移动端评测问卷功能-LMLPHPjQuery实现移动端评测问卷功能-LMLPHPjQuery实现移动端评测问卷功能-LMLPHP

需求:

1.有10道测试题目,单选,选中答案之后,500ms后自动跳转至下一题

2.如果当前题目没有选择答案,将弹窗提示“请选择答案!”

3.点击“上一题”,“下一题”将实现跳转题目,第一题的时候,“上一题”按钮为灰色

4.第10题选择答案之后将选中的题目分数相加,自动出现评测结果,对评测结果不满意的可以点击“重新测评”再测一次

5.单页功能,不实现页面跳转

构思:

1.单选按钮需要替换背景图片,可以通过class来切换,并用另外一个class来标识选中

2.用li来代表每一道题

需要使用的图片

{

}

jq部分:

1.定义会用到的变量

       // 当前题目索引
var currentSubjectIndex = 1;
// 总题数
var subjectTotal = subjectArray.length;
// 上一题按钮
var $preBtn = $("#preBtn");
// 下一题按钮
var $nextBtn = $("#nextBtn");
// 题目容器
var $subjectBox = $("#subjectBox");
// 总题数容器
var $total = $("#total"); // 进度条
var $scroller = $("#scroller"); //重新测评按钮
var $reset = $("#reset");

2.点击效果

    // 选中题目点击
$subjectBox.find("div.line").on("click", function(){
if(currentSubjectIndex >= 1){
$preBtn.addClass("blue");
}
       //get为选中的答案标识
$(this).find(".check-img").removeClass("uncheck").addClass("get");
$(this).siblings().find(".check-img").addClass("uncheck");
setTimeout(nextPage,300);
}); // 上一题按钮点击
$preBtn.on("click", function(){ prePage(); }); // 下一题按钮点击
$nextBtn.on("click", function(){ nextPage(); });
     //重新测评按钮点击
$reset.on("click", function(){ resetTest(); });

3.函数

        /**
* 初始化题目容器
*/
function initSubjectBox(){
var subjectHtml = '';
for(var i=0; i<subjectArray.length; i++){
subjectHtml += getSubjectHtml(subjectArray[i], i+1);

$("#index_" + currentSubjectIndex).addClass("active"); // 改变进度条
changeScroller();
} /**

html += ''
+'<div class="line" value="' + subjectItem.point + '">'

+'<span>' + subjectItem.content + '</span>'
+'<div class="check-img uncheck">'+'</div>'
+'</div>';
}
return html;
} /**

*/
function changeScroller(){
$scroller.width(currentSubjectIndex/subjectTotal * 100 + "%");
} /**

*/
function getTotalPoint(){
var result = 0;
var selectedOptionArray = $subjectBox.find(".get");
$(selectedOptionArray).each(function(){
result += parseInt($(this).parent().attr("value"));
});
return result;
} /**

*/
function prePage(){
//console.log(currentSubjectIndex);
if(currentSubjectIndex <= 1){return;}
if(currentSubjectIndex == 2){$preBtn.removeClass("blue");}
currentSubjectIndex--;
flipPage();
} /**

}
var nopass = $("#index_" + currentSubjectIndex).find(".get").length == 0 ? true : false;
if(nopass){
$("#choice-tip").fadeIn();
setTimeout("$('#choice-tip').fadeOut()",1000);
return;
}
if(currentSubjectIndex == subjectTotal){
          //得出结果
var result = getTotalPoint();
//console.log("您的得分是:" + result);
var imgSrc = $("#result-img"),
resultType = $("#result-type"),
maxMoney = $("#max-money"),
investMoney = $("#invest-money"); if(result >= 0 && result <= 22){
imgSrc.attr("src","img/risk-test/result1.png");
resultType.html("评测结果:保守型")
maxMoney.html("10万元");
investMoney.html("30,000.12元")
}else if(result >= 23 && result <= 44){
imgSrc.attr("src","img/risk-test/result2.png");
resultType.html("评测结果:稳健型")
maxMoney.html("20万元");
investMoney.html("30,000.12元")
}else if(result >= 45 && result <= 66){
imgSrc.attr("src","img/risk-test/result3.png");
resultType.html("评测结果:平衡型")
maxMoney.html("30万元");
investMoney.html("30,000.12元")
}else if(result >= 67 && result <= 88){
imgSrc.attr("src","img/risk-test/result4.png");
resultType.html("评测结果:积极型")
maxMoney.html("40万元");
investMoney.html("30,000.12元")
}else{
imgSrc.attr("src","img/risk-test/result5.png");
resultType.html("评测结果:激进型")
maxMoney.html("50万元");
investMoney.html("30,000.12元")
}
$(".risk").fadeOut();
$(".result-box").fadeIn();
return;
}
currentSubjectIndex++;
flipPage()
} /**
* 翻页
*/
function flipPage(){
$subjectBox.find("li").removeClass("active");
$("#index_" + currentSubjectIndex).addClass("active");
$("#current").html(currentSubjectIndex);
changeScroller();
} /**
* 重新测评
*/
function resetTest(){
currentSubjectIndex = 1;
$(".risk").fadeIn();
$(".result-box").fadeOut();
$preBtn.removeClass("blue");
$(".check-img").removeClass("get").addClass("uncheck");
flipPage();
}

在得出结果那里,总分的分层范围中,resultType,maxMoney,investMoney实际为后台读取的数据。
