点击确定按钮生成表达式，并在页面显示
btn.onclick = function(){ var strLi = ‘‘, strInput = ‘‘; getCount = document.getElementsByClassName(‘inputer‘)[0].getElementsByTagName(‘input‘)[0].value, getRange = document.getElementsByClassName(‘inputer‘)[0].getElementsByTagName(‘input‘)[1].value; console.log(getCount+getRange); for( var i = 0; i < getCount; i++){ detailArr.push(deepClone(obj)); expreArr.push(createExpression(getRange)); detailArr[i].expression = expreArr[i]; } for(var i = 0; i < detailArr.length; i++){ answerArr.push(calculate(detailArr[i].expression)); detailArr[i].answer = answerArr[i]; } count = getCount; range = getRange; if(getCount != null && getRange != null){ for(var i = 0; i < getCount; i++){ strLi += ‘<li>‘+(i+1)+‘、 ‘+ detailArr[i].expression + ‘= <input type="text"></li>‘; strInput +=‘‘; } $(‘#content‘).append(strLi); $(‘.response‘).append(strInput); } }
点击提交按钮显示题目答案并统计答题信息
submit.onclick = function(){ var strDiv = ‘‘, strAnswer = ‘‘, rightCount = 0, wrongCount = 0, score = 0; var respArrays = document.getElementById(‘content‘); for( var i = 0; i < detailArr.length; i++){ // console.log(respArray[i].value+" "+detailArr[i].answer); // console.log(‘index:‘+i); var responseValue = respArrays.getElementsByTagName(‘li‘)[i].getElementsByTagName(‘input‘)[0].value; if(responseValue == detailArr[i].answer && responseValue!= null){ $(‘#content li:eq(‘+i+‘)‘).append(‘<div class="rightMsg"></div>‘); // strDiv += "<div class=‘rightMsg‘></div>" ; detailArr[i].status = ‘right‘; rightCount++; console.log(1); }else{ // strDiv += "<div class=‘wrongMsg‘></div>"; $(‘#content li:eq(‘+i+‘)‘).append(‘<div class="wrongMsg"></div><input type="text" value="‘+detailArr[i].answer+‘">‘); detailArr[i].status = ‘wrong‘; wrongCount++; console.log(0); } detailArr[i].response = responseValue; strAnswer +=‘<input type="text"value="‘+ detailArr[i].answer+‘"readonly>‘; } $(‘.status‘).append(strDiv); $(‘.answer‘).append(strAnswer); //打印统计结果 var oResults = document.getElementsByClassName(‘wrapper‘)[0].getElementsByClassName(‘bottom‘)[0]; //正确数 oResults.getElementsByClassName(‘content‘)[0].getElementsByTagName(‘input‘)[0].value = rightCount; //错误数 oResults.getElementsByClassName(‘content‘)[0].getElementsByTagName(‘input‘)[1].value = wrongCount; //得分|正确率 oResults.getElementsByClassName(‘result‘)[0].getElementsByTagName(‘input‘)[0].value = Math.round(rightCount/(rightCount + wrongCount) * 100); }
控制台显示题号
点击右下角保存，通过ajax将数据发送到php后台并将题目以txt格式保存到本地
download.click = function(){ $ajax({ type:‘POST‘, url:‘./getDatas.php‘, data:{detailArr}, success:function(){ alert("保存成功！"); window.location.reload(); }, error:function(){ alert("保存失败"); } }) }后台
<?php head(‘content-type:text/html;charset="utf-8"‘); error_reporting(0); $dataArrays = $_Post[‘detailArr‘]; $arrayLength = count(dataArrays); $myfile = fopen("result.txt", "w") or die("Unable to open file!"); for($x = 0; $x < $arrayLength; $x++){ $txt= $dataArrays[$x]+"\n"; fwrite($myfile, $txt); } fclose($myfile); `
支持生成上万道四则运算题，但当前尚未进行优化，因此过程稍慢，后续会在这方面进行改善
总结：
当前未完成分数、真分数的计算、难度的设置以及表达式的查重，在后续版本会加以改善。
