Question

我正在进行freecodecamp的Wikipedia Viewer挑战，当我通过找到的页面进行迭代时，列表的第一项不包含指向Wikiepdia页面的链接。那是为什么？

JS代码：

function getData(){
  var search = $("#searchBar").val();
  var url = baseUrl + '/w/api.php?action=query&format=json&origin=*&list=prefixsearch&psoffset=max&pssearch='+search;

$.ajax( {
  url: url,
  dataType: 'json',
  type: 'GET',
  success: function(data) {
    var html="";
    var entries = data.query.prefixsearch;
    console.log(url);
    html+="<ul class='items'>";
    for(var i=0;i<entries.length;i++){
      html+="<li><h3>"+entries[i].title+"</h3><a href='http://en.wikipedia.org/?curid="+entries[i].pageid+"'</a></li>";
  }

   html+="</ul>";
   $(".entries").html(html);
  }
});
}

Html代码：

<div class="entries">

</div>

Answer 1

正如James在评论中指出的那样，您的代码输出>而没有结束html+="<li><h3>"+entries[i].title+"</h3><a href='http://en.wikipedia.org/?curid="+entries[i].pageid+"'</a></li>";且没有文字。

变化：

html+="<li><a href='http://en.wikipedia.org/?curid="+entries[i].pageid+"'><h3>"+entries[i].title+"</h3></a></li>";

进入这个：

function getData() {
var search = $("#searchBar").val();
var url = baseUrl + '/w/api.php?action=query&format=json&origin=*&list=prefixsearch&psoffset=max&pssearch=' + search;

$.ajax({
    url: url,
    dataType: 'json',
    type: 'GET',
    success: function(data) {
        var html = "";
        var entries = data.query.prefixsearch;
        console.log(url);
        html += "<ul class='items'>";
        for (var i = 0; i < entries.length; i++) {
            html+="<li><a href='http://en.wikipedia.org/?curid="+entries[i].pageid+"'><h3>"+entries[i].title+"</h3></a></li>";
        }

        html += "</ul>";
        $(".entries").html(html);
    }
});
}

完整代码

#Test array
$array = "Dog", "Cat", "Mouse", "Tiger"

#Location of the Excel file to edit
$FileLoc = "Q:\Cutsheet.xlsx"

#Create Excel Com Object, and display it
$excel = new-object -com Excel.Application
$excel.visible = $true

#Open Workbook
$workbooks = $excel.workbooks.Open($FileLoc)
$worksheets = $workbooks.Worksheets
$worksheet = $worksheets.item("DATA")

#opens inventory workbook
$source = $excel.workbooks.Open("Q:\inventory.xlsx")
$sourceSheets = $source.Worksheets

<# 
#This loop will search for match element of the array with a corresponding cell on an excel spreadsheet.
#That cell is grouped with several names of inventory worksheet names. The script will copy each inventory
#and append it to the existing cutsheet.
#>

foreach($element in $array) {
for ($i = 9; $i -lt 20; $i++) {
if ($worksheet.Cells.Item($i, 1).Text -eq $element) {
$j = 2
while ($worksheet.Cells.Item($i, $j).Text -ne "") {
Write-Host $worksheet.Cells.Item($i, $j).Value2
$name = $worksheet.Cells.Item($i, $j).Value2
$sourceSheet = $sourceSheets.Item($name)
$sourceSheet.Copy([system.type]::missing, $worksheets)
$j++
}
}
}
}

为什么我的无序列表中的第一项不包含链接？
