使用Jquery根据td值更改行颜色 [英] Change Row Color based on td value using Jquery
问题描述
我有一个从数据库填充的表格。我有2个条件需要申请
- 在表格中应用斑马条纹(已完成)
- 将行颜色更改为红色td值
`
< tr class =alt>
< td class =status>< input type =textvalue =One>< / td>
< td class>收到< / td>
< / tr>
< tr class =alt>
< td class =status>< input type =textvalue =One>< / td>
< td class>收到< / td>
< / tr>
< tr class =alt>
< td class =status>< input type =textvalue =Zero>< / td>
< td class>收到< / td>
< / tr>
< tr class =alt>
< td class =status>< input type =textvalue =One>< / td>
< td class>收到< / td>
< / tr>
< tr class =alt>
< td class =status>< input type =textvalue =Zero>< / td>
< td class>收到< / td>
< / tr>
`
$(document).ready(function()
{
$(tr.alt:even)。css(background-color,#f0f8ff );
$(tr.alt:odd)。css(background-color,#fcfceb);
});
$(document).ready(function(){
$('。status.val():contains(Zero)')。closest('tr.alt') .css('background-color','#cd0000');
});
我想根据输入值来更改行颜色
< td class =status>< input type =textvalue =One>< / td>

这是我迄今为止所做的一件小事 感谢您的帮助。 要更改 tr(你使用v 1.6.4而不是最新的,所以我们需要绑定而不是on) 你的HTML有点搞砸了。您缺少引号, http://jsfiddle.net/MMEhc/158/ 编辑:更新版以适应手动更改的值,而不仅仅是那些被输出的值(因为我理解的问题是) http://jsfiddle.net/MMEhc/159/ 你会看到我移动了背景颜色从HTML中移入CSS中,以便于操作。我还调整了偶数行或奇数行的红色。 I have a table that gets populated from a database. I have 2 conditions that i need to apply `
` I wanna change the row color based on the input value Here is a fiddle of what I've done so far Would appreciate the help. To change the tr (you're using v 1.6.4 instead of latest so we need bind instead of on) Your HTML is a bit messed up though. You have missing quotes and http://jsfiddle.net/MMEhc/158/ EDIT: Updated version to suit the values being changed manually, not just those that are outputted (as I understood the question to be) http://jsfiddle.net/MMEhc/159/ You'll see I moved the background colours out of the HTML and into the CSS to make it easier to manipulate. I also adjusted the red for even or odd rows. 这篇关于使用Jquery根据td值更改行颜色的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
$(document) .ready(function(){
$(tr.alt:even)。addClass(even);
$(tr.alt:odd)。addClass( ; odd);
$('td.status input')。bind('change keyup',function(){
var tr = $(this).closest('tr');
if($(this).val()=='Zero')tr.addClass('zero');
else tr.removeClass('zero');
))。trigger('change'); //触发器在加载
时运行这个动作});
tr.odd
{
background-color:#fcfceb;
}
tr.even
{
background-color:#f0f8ff;
}
tr.odd.zero
{
background-color:#ff0000;
}
tr.even.zero
{
background-color:#cc0000;
}
< td class>
无效。 $ b
<tr class="alt">
<td class="status"><input type="text" value="One"></td>
<td class>Received</td>
</tr>
<tr class="alt">
<td class="status"><input type="text" value="One"></td>
<td class>Received</td>
</tr>
<tr class="alt">
<td class="status"><input type="text" value="Zero"></td>
<td class>Received</td>
</tr>
<tr class="alt">
<td class="status"><input type="text" value="One"></td>
<td class>Received</td>
</tr>
<tr class="alt">
<td class="status"><input type="text" value="Zero"></td>
<td class>Received</td>
</tr>
$(document).ready(function()
{
$("tr.alt:even").css("background-color", "#f0f8ff");
$("tr.alt:odd").css("background-color", "#fcfceb");
});
$(document).ready(function() {
$('.status.val():contains("Zero")').closest('tr.alt').css('background-color', '#cd0000');
});
<td class="status"><input type="text" value="One"></td>
$(document).ready(function(){
$("tr.alt:even").addClass("even");
$("tr.alt:odd").addClass("odd");
$('td.status input').bind('change keyup', function(){
var tr=$(this).closest('tr');
if ($(this).val()=='Zero') tr.addClass('zero');
else tr.removeClass('zero');
}).trigger('change'); // the trigger is to run this action on load
});
tr.odd
{
background-color:#fcfceb;
}
tr.even
{
background-color:#f0f8ff;
}
tr.odd.zero
{
background-color:#ff0000;
}
tr.even.zero
{
background-color:#cc0000;
}
<td class>
is invalid.
