我需要在表中编辑值,其中行/单元格是由Bootgrid动态生成的,因此它们没有html id。我目前通过转到tr:nth-child来执行此操作,但这仅在我为rowID设置的值对应于表中的该位置时才有效。
例如:如果我从表中删除第3项,则rowID = 4的项目现在是tr的第3个子项,以下代码将编辑错误的单元格。
我需要能够找到要按ID编辑的正确行,而不是在网格中的位置。我昨天发布了一个类似的问题,但我已经改进了这个问题,以便更好地澄清我想要做的事情。
// I get the rowID by clicking an Edit button on the table row, like this:
rowID = $(this).data("row-id");
// This is what I'm doing now to edit the table:
$('#or-table tr:nth-child(' + rowID + ') td:nth-child(3)').html($('#aff-selector').val());
$('#or-table tr:nth-child(' + rowID + ') td:nth-child(4)').html($('#editor-code').val());
$('#or-table tr:nth-child(' + rowID + ') td:nth-child(5)').html($('#editor-lat').val());
$('#or-table tr:nth-child(' + rowID + ') td:nth-child(6)').html($('#editor-long').val());

<!-- This is the table: -->
<table id="or-table" class="table table-condensed table-hover table-striped bootgrid-table">
<thead>
<tr>
<th data-column-id="id" data-identifier="true" data-type="numeric">ID</th>
<th data-column-id="aff" align="center">Affiliation</th>
<th data-column-id="code">Symbol Code</th>
<th data-column-id="lat">Latitude</th>
<th data-column-id="long">Longitude</th>
<th data-column-id="commands" data-formatter="commands" data-sortable="false">Commands</th>
</tr>
</thead>
<tbody>
<!-- These tr/td generated by Bootgrid: -->
<tr data-row-id="1">
<td class="select-cell" style="{{ctx.style}}">
<td class="text-left" style="">1</td>
<td class="text-left" style="">H</td>
<td class="text-left" style="">SHG-EVAI-------</td>
<td class="text-left" style="">35.39135902572556</td>
<td class="text-left" style="">-116.52048110961914</td>
<td class="text-left" style="">
</tr>
<tr data-row-id="2">
<td class="select-cell" style="{{ctx.style}}">
<td class="text-left" style="">2</td>
<td class="text-left" style="">H</td>
<td class="text-left" style="">SHG-EVAT-------</td>

您可以使用以下选择器

元素。
显然,您应该根据您想要实现的目标更改<!DOCTYPE html>
<html>
<head>
<title>Blur Testing</title>
<meta name="content-type" content="text/html; charset=UTF-8">
<style>
body {
margin: 0;
}
#item {
background: url("http://i66.tinypic.com/2z6uq9f.jpg");
background-size: cover;
background-position: center;
}
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript"></script>
</head>
<body>
<canvas id="item"></canvas>
<script>
var canvas = document.getElementById('item');
var ctx = canvas.getContext('2d'),
img = new Image,
radius = 30;
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
$('#item').css({
"-webkit-filter": "blur(0px)",
"filter": "blur(0px)"
});
$(img).on('load', function () {
$('#item').mouseover(function (e) {
erase(getXY(e));
}).mousemove(function (e) {
erase(getXY(e));
//setTimeout(redraw(getXY(e)), 400);
});
ctx.drawImage(img, 0, 0);
ctx.globalCompositeOperation = 'destination-out';
});
img.src = 'http://i64.tinypic.com/14mt7yx.jpg';
img.width = window.width;
img.height = window.height;
function getXY(e) {
var r = $('#item')[0].getBoundingClientRect();
return {x: e.clientX - r.left, y: e.clientY - r.top};
}
// function redraw(pos) {
// ctx.globalCompositeOperation = 'source-in';
// ctx.beginPath();
// ctx.arc(pos.x, pos.y, radius, 0, 2 * Math.PI);
// ctx.closePath();
// ctx.fill();
// };
function erase(pos) {
ctx.globalCompositeOperation = 'destination-out';
ctx.beginPath();
ctx.arc(pos.x, pos.y, radius, 0, 2 * Math.PI);
ctx.closePath();
ctx.fill();
}

这在代码中太复杂了。 ;)
// you have the row already? Use it!
var columns = $('td', this);
// 'eq()' gives you the column by index
columns.eq(3).html($('#aff-selector').val());
columns.eq(4).html($('#editor-code').val());
columns.eq(5).html($('#editor-lat').val());
columns.eq(6).html($('#editor-long').val());
或者如果您想选择rowID
:
var columns = $('tr[data-row-id=' + rowID + '] td');
columns.eq(3).html($('#aff-selector').val());
columns.eq(4).html($('#editor-code').val());
columns.eq(5).html($('#editor-lat').val());
columns.eq(6).html($('#editor-long').val());

检查出来:https://jsfiddle.net/fsbwhhu4/
function find_in_table(table, column, row) {
var table = $(table)
var column_index = table.find('thead tr [data-column-id=' + column + ']').index()
var row = table.find('tr[data-row-id="' + row + '"]')
return row.find('td').eq(column_index)
}
// Usage:
find_in_table('#or-table', 'lat', 1)
答案 3 :(得分:0)
如果您在任何单元格中都有 Id ,则以下内容应该适用
document.getElementById("myID "+tempIdx).parentNode.parentNode.rowIndex;
提供的表格采用以下格式
<table>
<tr>
<td>
<p id="myID 1" />
</td>
<td></td>
</tr>
<td></td>
<td>
<p id="myID 2" />
</td>
</tr>
<td>
<p id="myID 3" />
</td>
</tr>
