jQuery在postion插入表行 [英] JQuery insert table row at postion

问题描述

我一直在研究能够将行插入到html表的解决方案。它非常棘手。我发现了一些有用的东西，但仅限于第一个插入。我无法弄清楚我做错了什么。

我有一个带3列的基本表每个表都有一个按钮，允许在2行之间插入一行。我在这个网站上搜索了一个解决方案，并得到了一个jquery解决方案，即当我按下按钮时，它会添加我想要的行。但是当我在插入最后一行后插入另一行时，该行被插回1位，下一次我按下插入的2行后面的按钮等等。我无法弄清楚什么即时通讯做错了任何人知道为什么它做这是什么？

更好的是有更好的方法来做到这一点？即在任何位置向表中添加一行？

JQuery代码;

 <脚本> 
 $（document）.ready（function（）{
 $（。addRow）。click（function（event）{
 
 //获取按钮id该行
 var $ id = this.id; 
 var $ totrecords; 
 var $ newrow; 
 var $ totalrowsadded; 
 //获取单击按钮的ID 
 $ id = $ id.replace（add_，）; 
 
 $ totrecords = document.getElementById（'totalrecords'）。value; 
 $ totrecords ++; 
 
 //商店添加的行数
 $ totalrowsadded = document.getElementById（'totalrowsadded'）。value; 
 $ totalrowsadded ++; 
 document.getElementById（'totalrowsadded'） .value = $ totalrowsadded; 
 
 //更新记录数
 document.getElementById（'totalrecords'）。value = $ totrecords; 
 
 var $ html =' < tr class =newrow>< td>'+ $ totrecords +'< button type =buttonclass =addRowid =add _'+ $ totrecords +'> add< / button><<< ; / td>< td>< label for =ProductHeight'+ $ totrecords +'> height&l t; / label>< input name =data [Product] [height'+ $ totrecords +']type =textvalue =0id =ProductHeight'+ $ totrecords +'/>< td>< td>< label for =ProductWidth'+ $ totrecords +'>宽度< / label>< input name =data [Product] [width'+ $ totrecords +']type =text value =0id =ProductWidth'+ $ totrecords +'/>< / td>< td>< label for =ProductPrice'+ $ totrecords +'> List Price< / label>< input name =data [Product] [price'+ $ totrecords +']type =textid =ProductPrice'+ $ totrecords +'/>< / td>< / tr>'; 
 
 
 $ newrow = parseInt（$ id）+1; 
 alert（'new row insert at'+ $ newrow）; （$ html）; 
 
 $（'＃productstable> tbody> tr：nth-​​child（'+ $ newrow +'）'）。 
 
 
}）; 
}）; 
 
< / script> 
  

我的表格是这样的;

 < table id =productstable> 
< tr> 
< th>插入< / th> 
< th>高度< / th> 
< th>宽度< / th> 
列表价格< / th> 
< / tr> 
 
< tbody> 
< tr id =0> 
< td> 0：< button type =buttonclass =addRowid =add_0> add< / button>< / td>

< / table> 
  

解决方案

您希望JQuery 追加函数：

  $（'＃productstable TBODY'）。append（$ html）; 
  

要在包含点击按钮的行后添加一行，请使用以下命令：

（$ html）;

  $（this）.closest（'TR'）。 
  

最接近找到最近的TR，然后在之后放置它。

Ive been working on a solution to being able to insert a row to a html table. Its been quite tricky. Ive found something that works but only for the first "insert". I cant figure out what im doing wrong.

Ive a basic table with 3 colums each table has a button to allow the insertion of a row between 2 rows. Ive searhed on this site for a solution and got a jquery solution that works i.e when i press the button it adds the row where i want it. But when i add another row after where i inserted the last row, the row is inserted 1 position back, the next time i press the button its inserted 2 rows back etc. I cant figure out what im doing wrong any one know why its doing this?

Even better is there a better way to do this? i.e add a row into a table at any postion?

JQuery code;

<script>
$(document).ready(function(){
    $(".addRow").click(function(event){

    //get the button id to get the row
    var $id=this.id;
    var $totrecords;
    var $newrow;
    var $totalrowsadded;
    //get id of clicked button
    $id=$id.replace("add_", "");

    $totrecords=document.getElementById('totalrecords').value;
    $totrecords++;

    //store number of rows added
    $totalrowsadded=document.getElementById('totalrowsadded').value;
    $totalrowsadded++;
    document.getElementById('totalrowsadded').value=$totalrowsadded;

    //update record count
    document.getElementById('totalrecords').value=$totrecords;

    var $html='<tr class="newrow"><td>'+$totrecords+'<button type="button" class="addRow" id="add_'+$totrecords+'">add</button></td><td><label for="ProductHeight'+$totrecords+'">height</label><input name="data[Product][height'+$totrecords+']" type="text" value="0" id="ProductHeight'+$totrecords+'"/></td><td><label for="ProductWidth'+$totrecords+'">width</label><input name="data[Product][width'+$totrecords+']" type="text" value="0" id="ProductWidth'+$totrecords+'"/></td><td><label for="ProductPrice'+$totrecords+'">List Price</label><input name="data[Product][price'+$totrecords+']" type="text" id="ProductPrice'+$totrecords+'"/></td></tr>';


    $newrow=parseInt($id)+1;
    alert('new row insert at '+$newrow);

    $('#productstable > tbody> tr:nth-child(' + $newrow + ')').after($html);    


});
});

</script>

My table looks like this;

<table id="productstable">
    <tr>
        <th>Insert</th>
        <th>Height</th>
        <th>Width</th>
        <th>List price</th>
    </tr>

    <tbody>
    <tr id="0">
        <td>0 :<button type="button" class="addRow" id="add_0">add</button></td>
        <td><label for="ProductHeight0">height</label><input name="data[Product][height0]" type="text" value="115" id="ProductHeight0"/></td>
        <td><label for="ProductWidth0">width</label><input name="data[Product][width0]" type="text" value="595" id="ProductWidth0"/></td>
        <td><label for="ProductPrice0">List Price</label><input name="data[Product][price0]" type="text" id="ProductPrice0"/></td>
    </tr>

    <tr id="1">
        <td>1 :<button type="button" class="addRow" id="add_1">add</button></td>
        <td><label for="ProductHeight1">height</label><input name="data[Product][height1]" type="text" value="140" id="ProductHeight1"/></td>
        <td><label for="ProductWidth1">width</label><input name="data[Product][width1]" type="text" value="295" id="ProductWidth1"/></td>
        <td><label for="ProductPrice1">List Price</label><input name="data[Product][price1]" type="text" id="ProductPrice1"/></td>
    </tr>

    <tr id="2">
        <td>2 :<button type="button" class="addRow" id="add_2">add</button></td>
        <td><label for="ProductHeight2">height</label><input name="data[Product][height2]" type="text" value="140" id="ProductHeight2"/></td>
        <td><label for="ProductWidth2">width</label><input name="data[Product][width2]" type="text" value="395" id="ProductWidth2"/></td>
        <td><label for="ProductPrice2">List Price</label><input name="data[Product][price2]" type="text" id="ProductPrice2"/></td>
    </tr>

    <tr id="3">
        <td>3 :<button type="button" class="addRow" id="add_3">add</button></td>
        <td><label for="ProductHeight3">height</label><input name="data[Product][height3]" type="text" value="140" id="ProductHeight3"/></td>
        <td><label for="ProductWidth3">width</label><input name="data[Product][width3]" type="text" value="495" id="ProductWidth3"/></td>
        <td><label for="ProductPrice3">List Price</label><input name="data[Product][price3]" type="text" id="ProductPrice3"/></td>
    </tr>

    </tbody>
</table>

解决方案

You want the JQuery append function:

$('#productstable TBODY').append($html); 

To add a row after the row containing the button that was clicked, use this:

$(this).closest('TR').after($html);

The closest function walks up the tree to find the nearest TR, then after will put it after it.
