使用 jQuery 更改表格元素内容

【中文标题】使用 jQuery 更改表格元素内容【英文标题】:Change a table element content with jQuery 【发布时间】:2016-10-27 03:13:16 【问题描述】:我正在尝试修改特定<td>
的内容,但未成功。
想法是将脚本词'S/JUROS'
从8x
更改为' C/JUROS'
。
对最好的方法有什么建议吗?我已经设法挽救了数组中的值,但在这个阶段被抓住了。

jQuery(document).ready(function($)
if (jQuery(".tbl-payment-system").length)
var getTexts = [];
$(".tbl-payment-system tr td.parcelas").each(function()
getTexts.push($(this).text())
);
var resultTexts = '"' + getTexts.join('", "') + '"';
console.log(resultTexts);
);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tbl1" class="tbl-payment-system" style="display: table;">
<tbody>
<tr class="even">
<th class="parcelas">Nº de Parcelas</th>
<th class="valor">Valor de cada parcela</th>
</tr>
<tr class="even">
<td class="parcelas">X S/JUROS</td>
<td>R$ 600,00</td>
</tr>
<tr>
<td class="parcelas">2X S/JUROS</td>
<td>R$ 300,00</td>

奥拉! Estoutentando modificar o conteúdo de umas 'tds' específicas sem 继任者。 A ideia é com o script alterar a palavra 'S/JUROS' por 'C/JUROS' 是 8x 的一部分。 Alguma sugestão para a melhor forma de fazer 伊索? Já consegui resgatar os valores num array, mas travei nessa 埃塔帕。

【问题讨论】:
是否要求仅从包含8x
转发的td
更改文本?
您想更改元素的实际文本还是只将更改后的文本保存到数组中?
【参考方案1】:
您可以使用:contains()
、.add()
、通用兄弟选择器~
、.map()
、.replace()
、.get()
。请注意,不清楚要求是更改 html
td
元素的文本还是仅更改存储在数组中的文本?如果预期结果是要更改 td
元素文本,您可以使用 .text(function(index, originalText) )
返回新文本
jQuery(document).ready(function($)
if (jQuery(".tbl-payment-system").length)
var getTexts = [];
var x = $(".tbl-payment-system tr:contains(8X)");
var resultTexts = x.add($("~ tr", x)).map(function()
return $("td.parcelas", this).text(function(_, text)
return text.replace(/S(?=\/)/, "C")
).text()
).get();
console.log('"' + resultTexts.join('", "') + '"');
);

谢谢大家。所有解决方案都很棒。他们帮了很多忙!【参考方案2】:看看这个
$("td").each(function()
if (parseInt($(this).text()) >= 8)
$(this).text(($(this).text()).replace("S/JUROS","C/JUROS"));
)

谢谢大家。所有解决方案都很棒。他们帮了很多忙!【参考方案3】:使用 :contains
找到 8X,然后找到它的 parent
和 nextUntil
结尾。然后 addBack
包含 8X 并获取每一行 :first-child
。
然后each
他们更新文本:-
var elements = $('table td:contains(8X)').parent().nextUntil().addBack().children(':first-child');
elements.each(function()
$(this).text($(this).text().replace('S/JUROS', 'C/JUROS'));
);
