javascript - $.ajax({}) 能否在js函式中呼叫?
1.想做問卷調查。頁面中有多個題目，每個題目下方有多個選項，最後有一個提交按鈕，提交時判斷使用者是否登入。題目和選項都是在jsp頁面中透過$.ajax從後台動態取得以html形式顯示在前台。現在提交時需要取得選擇的項目和題目將其存入後台的資料庫中，以便後台統計。
2.form表單
<form id="myform" name="myform" method="post">
<p class="sub730">
<p class="rightTitleStyle" id="rightTitle">
<span>有奖调查</span>
</p>
<p id="contentp">
<p class="newsLeftLayoutOp sceneRightLayout">
<p class="newsDetailContent">
<h2>${iyInvestigate.title}</h2>
<p class="newsDetailConMsg">
<span>发布时间：</span> <span>${iyInvestigate.createTime}</span> <span>活动结束时间：</span>
<span>${iyInvestigate.endtime}</span>
</p>
<p>
<span>${iyInvestigate.summary}</span>
</p>
<p id="optionp" class="test_content_nr"></p>
<p class="col-lg-9 col-lg-offset-3">
<a id="sub" href="javascript:void(0)" onclick="submitAnswer();">提交</a>
</p>
</p>
</p>
</p>
</p>
</p>
</form>
動態載入題目和選項
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
type : "post",
dataType : "json",
url : "${ctx}/website/yjdc/investigate/findInvestigateOptionByPage.action",
data : {"id":'${iyInvestigate.id}'},
success: function(rec){
var root = "${ctx}";
var optionlist = rec.investigateOpList;
var opHTML = '<ul>';
for(var i = 0;i<optionlist.length;i++){
var option = optionlist[i];
opHTML += '<li name="optionTitle" id="qu_0_'+i+'">';
opHTML += '<p name="pOptionTitle" class="test_content_nr_tt" id="p_0_'+i+'">'+ option.subject +'</p>';
opHTML += '<p class="test_content_nr_main">';
opHTML += '<ul>';
var deoption = option.options;
var deoptionsArr = new Array();
deoptionsArr = deoption.split("|"); //选项按照|分割开
for (var j = 0; j<deoptionsArr.length;j++){
opHTML += '<li name="liSelect" class="option">';
opHTML += '<input id="0_answer_'+i+'_option_'+j+'" class="radioOrCheck" name="answer'+i+'" type="radio">'+deoptionsArr[j];
//opHTML += '<label for="0_answer_'+i+'_option_'+j+'">'+'<p class="ue" style="display: inline;">'+deoptionsArr[j]+'</p>'+'</label>';
opHTML += '</li>';
}
opHTML += '</ul>';
opHTML += '</p>';
opHTML += '</li>';
}
opHTML += '</ul>';
$('#optionp').html(opHTML);
}
})
});
</script>提交函數submitAnswer()
function submitAnswer(){
var userid = "${sessionScope.user.id}";
if(userid == '')
{
alert("未登录，跳转登录页面！");
var dt = new Date();
var urlRoot = window.location.pathname;
var urlParameter = window.location.search;
var url = urlRoot + urlParameter;
window.location.href = "${pageContext.request.contextPath}/web/index/toLogin.action?url="+url+"&dt="+dt.getTime();
} else {
var k = document.getElementById('sub').innerText;
var investigateTitle = "${iyInvestigate.title}";
var indvestigateID = "${iyInvestigate.id}";
//获取同一个主题活动下的题目集合
var subjectTitleCountObj = document.getElementsByName("pOptionTitle");
//var optionSelectCount = document.getElementsByName("liSelect").length;
//获取每一道题目以及相应的选项
for (var k=0;k < subjectTitleCountObj.length;k++){
//ids = optionTitleCountObj[k].id;
//存储题目
var subject = $("#p_0_"+ k).text();
//var val_ = $('input[type="radio"][name="answer'+k+'"]:checked').val();
//存储选中的项
var selectItem = "";
var radios = document.getElementsByName("answer"+k);
for (r = 0; r < radios.length;r++) {
if (radios[r].checked) {
selectItem = radios[r].nextSibling.data;
}
};
$.ajax({
type : "post",
dataType : "json",
url : "${ctx}/website/yjdc/investigate/submitAnswer.action",
data : {"investigateTitle": ${iyInvestigate.title},"investigateID":${iyInvestigate.id},"subjectOp":subject,"selectItemOp":selectItem,"userid":${sessionScope.user.id}},
success : function(rec)
{
}
});
// for (var j=0; j<optionSelectCount;j++){
// var select = $("#0_answer_"+k+"_option_"+j).text();
// $("input:radio:checked").val();
// }
}
}
}
</script>3.現在的問題是在 function submitAnswer() {} 中加$.ajax({})根本進不了js函數submitAnswer。去掉$.ajax({})才可以執行submitAnswer函數。
請各位大神指教。
