我如何获得已检查商品的价格和名称？

static func findLinesContaining(_ searchTerms: String, forSearchScope scope: SearchScope) throws -> [TextLines] {

    guard let db = SQLiteDataStore.sharedInstance.TextDB else {
        throw DataAccessError.datastore_Connection_Error
    }

    // TODO: convert to SQLite.swift syntax rather than using a SQL string
    var statement: Statement? = nil
    switch scope {
    case .wholeCollection:
        statement = try db.run("SELECT bookId, chapterId, lineId, lineText" +
            " FROM lines" +
            " WHERE rowid IN (SELECT docid FROM fts_table" +
            " WHERE fts_table MATCH ?);", searchTerms)

    case .singleBook(let chosenBookId):
        statement = try db.run("SELECT bookId, chapterId, lineId, lineText" +
            " FROM lines" +
            " WHERE rowid IN (SELECT docid FROM fts_table" +
            " WHERE fts_table MATCH ?) AND bookId = ?;", [searchTerms, chosenBookId])
    }


    var returnList: [TextLine] = []
    for row in statement! {

        let line = TextLine()
        if let bookId = row[0] as? Int64,
            let chapterId = row[1] as? Int64,
            let lineId = row[2] as? Int64,
            let text = row[3] as? String {

            line.bookId = Int(bookId)
            line.chapterId = Int(chapterId)
            line.lineId = Int(lineId)
            line.lineText = text
        }

        returnList.append(line)
    }

    return returnList
}

var total = 0;
function test(item) {
  if (item.checked) {

    total += parseInt(item.value);

  } else {
    total -= parseInt(item.value);
  }
  //alert(total);
  document.getElementById('Totalcost').innerHTML = total + " ";
}

因为这只是<input type="checkbox" name="check_list[]" value="5" onClick="test(this);"><label>- Flag A</label> <- <span class="badge">Price: 5 credits</span><br /> <input type="checkbox" name="check_list[]" value="13" onClick="test(this);"><label>- Flag B</label> <- <span class="badge">Price: 13 credits</span><br /> <input type="checkbox" name="check_list[]" value="9" onClick="test(this);"><label>- Flag C</label> <- <span class="badge">Price: 9 credits</span><br /> <button type="button" class="btn btn-primary">Tototal price: <span class="badge"><span id="Totalcost">0</span></span> credits</button>，我想要显示名称和价格value="..."或id

Answer 1

这样的事情：你需要用＆＃34; id＆＃34;标记你的标签。和您输入的属性＆＃34; data-index＆＃34;。这不是一个完整的解决方案，因为你仍然需要处理取消选中操作，尽管如果你学习的话，你可以从这个例子开始。

＆＃13;

var total = 0;
   
function test(item) {
  if (item.checked) {
    var label = document.querySelector('#label'+ item.dataset.index);
    total += label.innerText + " - " + parseInt(item.value) + " credits; ";  
  }
  //alert(total);
  document.getElementById('Totalcost').innerHTML = "Labels selected: " + total;
}

＆＃13;

<input data-index="1" type="checkbox" name="check_list[]" value="5" onClick="test(this);">
<label id="label1">- Flag A</label>
<- <span class="badge">Price: 5 credits</span><br />
  <input  data-index="2" type="checkbox" name="check_list[]" value="13" onClick="test(this);">
<label  id="label2">- Flag B</label>
  <- <span class="badge">Price: 13 credits</span><br />
    <input type="checkbox" data-index="3" name="check_list[]" value="9" onClick="test(this);">
<label  id="label3">- Flag C</label>
    <- <span class="badge">Price: 9 credits</span><br />
      <button type="button" class="btn btn-primary">Tototal price: <span class="badge"><span id="Totalcost">0</span></span> credits</button>

@Beytulla，这适合我。

<html>
<head>
<script>
function buttonClick(){
   var total = 0;
   var type = "";
   for(var i=1;i<=3;i++) {
     var id = "check_list" + i;
     var label = "label" + i;
     var badge = "badge" + i;
     if (document.getElementById(id).checked!=null && document.getElementById(id).checked==true) {
        total += parseInt(document.getElementById(id).value);
        type += document.getElementById("label"+i).innerHTML + " : " + document.getElementById("badge"+i).innerHTML + ",";
      }
   }
  document.getElementById('Totalcost').innerHTML = total;
  document.getElementById('individual').innerHTML = type;
}
</script>
</head>
<body>
  <form method="post">
    <input type="checkbox" name="check_list1" id="check_list1" value="5" onClick="buttonClick(this);"><label id="label1"> Flag A</label>  <span class="badge" id="badge1">Price: 5 credits</span><br />

    <input type="checkbox" name="check_list2" id="check_list2" value="13" onClick="buttonClick(this);"><label id="label2"> Flag B</label>  <span class="badge" id="badge2">Price: 13 credits</span><br />

    <input type="checkbox" name="check_list3" id="check_list3" value="9" onClick="buttonClick(this);"><label id="label3"> Flag C</label>  <span class="badge" id="badge3">Price: 9 credits</span><br />

    <button type="button" class="btn btn-primary" onclick="buttonClick()">Total price: 
    <span class="badge"><span id="Totalcost">0</span></span> credits (<span id="individual">0</span>)</button>

  </form>
