如何在div容器中添加多个段落标记,新标记.

<div id="pcontainer">
  <p>recently added on top every time on click event recently added paragarph on top</p>
  <p>added before recent</p>
</div>

我正在使用追加,但每次我点击按钮它添加到底部我需要它添加在所有段的顶部请帮助.

我正在使用YQL调用以下URL

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22UTG.L%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=cbfunc

这将在JSON中返回以下内容

cbfunc({"query":{"count":"1","created":"2009-06-27T11:53:44Z","lang":"en-US","updated":"2009-06-27T11:53:44Z","uri":"http://query.yahooapis.com/v1/yql?q=select+*+from+yahoo.finance.quotes+where+symbol+in+%28%22UTG.L%22%29","diagnostics":{"publiclyCallable":"true","url":[{"execution-time":"468","content":"http://datatables.org/alltables.env"},{"execution-time":"634","content":"http://www.datatables.org/yahoo/finance/yahoo.finance.quotes.xml"},{"execution-time":"351","content":"http://download.finance.yahoo.com/d/quotes.csv?s=UTG.L&f=aa2bb2b3b4cc1c3c6c8dd1d2ee1e7e8e9ghjkg1g3g4g5g6ii5j1j3j4j5j6k1k2k4k5ll1l2l3mm2m3m4m5m6m7m8nn4opp1p2p5p6qrr1r2r5r6r7ss1s7t1t7t8vv1v7ww1w4xy"},{"execution-time":"357","content":"select * from csv where url=@url and columns='Ask,AverageDailyVolume,Bid,AskRealtime,BidRealtime,BookValue,Change&PercentChange,Change,Commission,ChangeRealtime,AfterHoursChangeRealtime,DividendShare,LastTradeDate,TradeDate,EarningsShare,ErrorIndicationreturnedforsymbolchangedinvalid,EPSEstimateCurrentYear,EPSEstimateNextYear,EPSEstimateNextQuarter,DaysLow,DaysHigh,YearLow,YearHigh,HoldingsGainPercent,AnnualizedGain,HoldingsGain,HoldingsGainPercentRealtime,HoldingsGainRealtime,MoreInfo,OrderBookRealtime,MarketCapitalization,MarketCapRealtime,EBITDA,ChangeFromYearLow,PercentChangeFromYearLow,LastTradeRealtimeWithTime,ChangePercentRealtime,ChangeFromYearHigh,PercebtChangeFromYearHigh,LastTradeWithTime,LastTradePriceOnly,HighLimit,LowLimit,DaysRange,DaysRangeRealtime,FiftydayMovingAverage,TwoHundreddayMovingAverage,ChangeFromTwoHundreddayMovingAverage,PercentChangeFromTwoHundreddayMovingAverage,ChangeFromFiftydayMovingAverage,PercentChangeFromFiftydayMovingAverage,Name,Notes,Open,PreviousClose,PricePaid,ChangeinPercent,PriceSales,PriceBook,ExDividendDate,PERatio,DividendPayDate,PERatioRealtime,PEGRatio,PriceEPSEstimateCurrentYear,PriceEPSEstimateNextYear,Symbol,SharesOwned,ShortRatio,LastTradeTime,TickerTrend,OneyrTargetPrice,Volume,HoldingsValue,HoldingsValueRealtime,YearRange,DaysValueChange,DaysValueChangeRealtime,StockExchange,DividendYield'"}],"javascript":{"instructions-used":"66024"},"user-time":"1537","service-time":"1810","build-version":"1949"},"results":{"quote":{"symbol":"UTG.L","Ask":"129.00","AverageDailyVolume":"354500","Bid":"128.50","AskRealtime":"129.00","BidRealtime":"128.50","BookValue":"0.00","Change_PercentChange":"+7.50 - +6.19%","Change":"+7.50","Commission":null,"ChangeRealtime":"+7.50","AfterHoursChangeRealtime":"N/A - N/A","DividendShare":"0.00","LastTradeDate":"6/26/2009","TradeDate":null,"EarningsShare":"0.00","ErrorIndicationreturnedforsymbolchangedinvalid":"N/A","EPSEstimateCurrentYear":"0.00","EPSEstimateNextYear":"0.00","EPSEstimateNextQuarter":"0.00","DaysLow":"122.00","DaysHigh":"128.75","YearLow":"36.25","YearHigh":"319.75","HoldingsGainPercent":"- - -","AnnualizedGain":"-","HoldingsGain":null,"HoldingsGainPercentRealtime":"N/A - N/A","HoldingsGainRealtime":null,"MoreInfo":"cred","OrderBookRealtime":"N/A","MarketCapitalization":null,"MarketCapRealtime":null,"EBITDA":"0","ChangeFromYearLow":"+92.50","PercentChangeFromYearLow":"+255.17%","LastTradeRealtimeWithTime":"N/A - <b>128.75<\/b>","ChangePercentRealtime":"N/A - +6.19%","ChangeFromYearHigh":"-191.00","PercebtChangeFromYearHigh":"-59.73%","LastTradeWithTime":"Jun 26 - <b>128.75<\/b>","LastTradePriceOnly":"128.75","HighLimit":null,"LowLimit":null,"DaysRange":"122.00 - 128.75","DaysRangeRealtime":"N/A - N/A","FiftydayMovingAverage":"125.714","TwoHundreddayMovingAverage":"100.63","ChangeFromTwoHundreddayMovingAverage":"+28.12","PercentChangeFromTwoHundreddayMovingAverage":"+27.94%","ChangeFromFiftydayMovingAverage":"+3.036","PercentChangeFromFiftydayMovingAverage":"+2.42%","Name":"UNITE GROUP","Notes":"-","Open":"122.00","PreviousClose":"121.25","PricePaid":null,"ChangeinPercent":"+6.19%","PriceSales":null,"PriceBook":null,"ExDividendDate":"14-Apr-04","PERatio":null,"DividendPayDate":"13-May-05","PERatioRealtime":null,"PEGRatio":null,"PriceEPSEstimateCurrentYear":null,"PriceEPSEstimateNextYear":null,"Symbol":"UTG.L","SharesOwned":null,"ShortRatio":null,"LastTradeTime":"11:35am","TickerTrend":"&nbsp;--=+++&nbsp;","OneyrTargetPrice":null,"Volume":"254927","HoldingsValue":null,"HoldingsValueRealtime":null,"YearRange":"36.25 - 319.75","DaysValueChange":"- - +6.19%","DaysValueChangeRealtime":"N/A - N/A","StockExchange":"London","DividendYield":null,"PercentChange":"+6.19%"}}}});

但我正在努力使用这些数据(我是jQuery和JSON的新手)

$.getJSON("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22UTG.L%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=cbfunc",
    function(data){

从这个例子只是闪烁受限的URL错误.

任何人的帮助 - 我只是解析数据并打印到屏幕.提前致谢!

我用jQuery制作这个代码来淡化图像(但不是移动鼠标的那个),所有图像同时褪色!

$(".playThumb").fadeTo("normal", 1);

$(".playThumb").hover(function() {
    $(".playThumb").each(function() {
        if ( $(this) != $(this) ) {
            $(this).fadeTo("fast", 0.3);
        }
    });
}, function() {
    $(".playThumb").each(function() {
            $(this).fadeTo("fast", 1);
    });
});

<a href="#"><img src="001.jpg" class="playThumb" />
<a href="#"><img src="002.jpg" class="playThumb" />
<a href="#"><img src="003.jpg" class="playThumb" />
<a href="#"><img src="004.jpg" class="playThumb" />

如果有人可以帮助我淡化所有其他图像,除了我指向鼠标的图像？

我想创建一个div容器,其中包含第一次访问我网站的消息.访问者将阅读它并单击"隐藏"按钮以永久消除它.

这是怎么做到的？

我专注于jQuery的输入字段:

$("input:text").focus();

输入字段中已存在一些文本值.当我对焦时,光标在最后一个字母后面闪烁,如何将光标放在第一个字母的正前方？

我想slideToggle在执行if语句和fadeIn效果之前等待效果完成.

div_to_move = $(this).parents("div.kind_div");

div_to_move.slideToggle();
if ($(this).html() == "+") {
    $(this).html("-");
    $("div.kind_to", td).append(div_to_move);
} else {
    $(this).html("+")
    $("div.kind_from", td).append(div_to_move);
}
div_to_move.fadeIn();

我能怎么做？

在下面的示例中:

<html>
<head>
<script src="some.js" type="text/javascript"></script>
<script type="text/javascript">

//???
//???

);

</script>
</head>
<body>
<table>
<tr id="parent_1">
<td>Parent 1</td>
</tr>
<tr class="child">
<td>Child 1</td>
</tr>
<tr class="child">
<td>Child 2</td>
</tr>
<tr id="parent_2">
<td>Parent2</td>
</tr>
</table>
</body>
</html>

我希望"Parent 1"文本更改为"Parent 1(2)",其中"2"是使用Java脚本或Jquery的给定父级的子级数.这怎么可能？

我是JQuery和Java脚本的新手.

请告诉我.

如果我有这样的div,我如何通过jquery选择当前链接:

<div id='navigation'>
  <a href='users/home'>home</a> |
  <a href='projects/browse'>home</a>
  <a href='discussions/browse'>home</a>
  <a href='search/dosearch'>home</a>
</div>

注意我试过:

$(document).ready(function(){
    $("#navigation a").click( function(event)
    {
       var clicked = $(this); // jQuery wrapper for clicked element
       // ... click-specific code goes here ...
       clicked.addClass('selected');
    });
});

但是,当我点击一个链接时,它会选择一个链接并添加类.selected但它重新加载页面以便导航到一个页面然后它全部消失.有小费吗？

谢谢
