我有一个JSON,我正在尝试使用JavaScript进行解析。迭代计数和附加的页面将是动态的。
预期结果
就像上面的图片一样,我能够从下面提到的json中获取动态迭代键。
Iteration.json
{
"count":[
{
"iteration1":[
{
"PageName":"T01_Launch"
},
{
"PageName":"T02_Login"
}
]
},
{
"iteration2":[
{
"PageName":"T01_Launch"
},
{
"PageName":"T02_Login"
}
]
}
]
}
当我单击迭代时,它必须为该特定迭代填充相应的页面名称,如预期结果图像所示。但是我实际上得到的是(请参见下图):
请找到我尝试的代码:
var pagenamearray = [];
$.getJSON("iteration.json", function(json) {
var hits = json.count;
var iterations, tnname, iteration;
for (var k in hits) {
var value;
if (hits.hasOwnProperty(k)) {
value = hits[k];
var iteratearray = [];
for (var j in value) {
if (value.hasOwnProperty(j)) {
j;
var check = value[j];
for (var i in check) {
if (check.hasOwnProperty(i)) {
var test = check[i];
for (var t in test) {
if (test.hasOwnProperty(t)) {
var pagename = JSON.stringify(t)
var arr = []
if (pagename.includes("PageName")) {
//alert("Key is " +pagename + ", value is" + JSON.stringify(test[t]));
for (var it = 0; it < hits.length; it++) {
if ((Object.keys(hits[it])).includes(j)) {
var pagenamevalue = test[t];
arr[it] = [];
arr.push(pagenamevalue);
}
}
}
//alert(arr)
}
pagenamearray.push(arr);
}
}
}
}
var row = document.createElement('div');
row.setAttribute("class", "row");
row.setAttribute("id", j)
var gridWidth = document.createElement('div');
gridWidth.setAttribute("class", "col-lg-12");
var panelRoot = document.createElement('div');
panelRoot.setAttribute("class", "panel panel-default");
var panelHeading = document.createElement('div');
panelHeading.setAttribute("class", "panel-heading");
var heading3 = document.createElement('a');
heading3.setAttribute("class", "panel-title");
var icon = document.createElement('i');
icon.setAttribute("class", "fa fa-long-arrow-right fa-fw");
heading3.appendChild(icon);
heading3.innerHTML = j;
heading3.setAttribute("onclick", "doit('" + j + "');");
panelHeading.appendChild(heading3);
/* var panelBody=document.createElement('div');
panelBody.setAttribute("class","panel-body");
panelBody.setAttribute("id","panellinks");*/
panelRoot.appendChild(panelHeading);
// panelRoot.appendChild(panelBody)
gridWidth.appendChild(panelRoot);
row.appendChild(gridWidth);
document.getElementById("analysis").appendChild(row);
}
}
}
});
function doit(value) {
var ul = document.getElementById(value);
if (ul != undefined) {
$("#" + "expandlinks").remove();
$("#" + value + value).remove();
}
var accordion = document.getElementById(value);
var panelBody = document.createElement('div');
panelBody.setAttribute("class", "panel-body");
panelBody.setAttribute("id", "expandlinks")
var tablediv = document.createElement('div')
var tablelink = document.createElement('a');
tablediv.appendChild(tablelink);
var graphdiv = document.createElement('div')
var graphlink = document.createElement('a');
graphdiv.appendChild(graphlink);
var recommndiv = document.createElement('div');
var recommendlink = document.createElement('a');
recommndiv.appendChild(recommendlink)
//alert(pagenamearray.length)
tablelink.innerHTML = pagenamearray;
/*graphlink.innerHTML="Timeline View";
recommendlink.innerHTML="Recommendations";*/
panelBody.appendChild(tablediv);
panelBody.appendChild(recommndiv);
panelBody.appendChild(graphdiv);
accordion.appendChild(panelBody);
}
任何有关如何实现这一目标的建议都会有很大帮助。预先感谢。

我认为问题在于如何将pagenamearray
分配给tablelink.innerHTML
。这会将数组转换为字符串,还将数组中的所有元素也转换为字符串,并用逗号将它们分开。但是,您的pagenamearray
也包含一些空数组。它们将在处理过程中转换为空字符串,但在它们之前和之后仍然会有逗号。
在上面的示例代码中,pagenamearray
的结尾为[[[],"T01_Launch"],[[],"T02_Login"],[null,[],"T01_Launch"],[null,[],"T02_Login"]]
-转换为字符串时,将得到",T01_Launch,,T02_Login,,,T01_Launch,,,T02_Login"
。因此,与其直接将其分配给innerHTML值,不如将其过滤掉空数组和空值。
