(Jquery) Find the contents of a td from a selected tr
提问by Andy
I am very new to JQuery, so appologies for what may be a very simple question.
我对 JQuery 很陌生,所以对于可能是一个非常简单的问题的应用程序。
I have a table, and when i click on a row, i want the cells details to be filled into a form:
我有一个表格,当我单击一行时,我希望将单元格详细信息填写到表格中:
so simple example
这么简单的例子
<table id="table">
<tr><td class="field1">1 </td><td class="field2">2 </td></tr>
</table>
<input id="input" type="text" />
So the JQuery:
所以JQuery:
$(document).ready(function() {
$('#table tr').click(function() {
$test = $(this).find('td').context.innerText) //problem here *
$('#input').val( );
})
- this returns the innertext of the tr (i.e "1 2"
- 这将返回 tr 的内部文本(即“1 2”
How am i supose to do it...
我该怎么做...
Thanks in advance
提前致谢

If you want the text of each cell to be captured as a singe space-separated string to populate your input, you can do this:
如果您希望每个单元格的文本被捕获为单个空格分隔的字符串以填充您的输入,您可以执行以下操作:
$(document).ready(function() {
$('#table tr').click(function() {
var $test = $(this).find('td').map(function() {
return $(this).text();
}).get().join(" ");
$('#input').val($test);
});
});
EDIT just call text(), e.g.:
编辑只是调用text(),例如:
var $field1 = $(this).find('td.field1').text();
回答by Mark Schultheiss
$(document).ready(function() {
var $test="";
$('#table tr>td').click(function() {
$test = $(this).text();
$('#input').val($test);
)};
});
alernative:
备选:
$(document).ready(function() {
var $test ="";
$('.field1, #table').click(function() {
$test = $(this).text();
$('#input').val($test);
)};
$('.field2, #table').click(function() {
$test = $(this).text();
$('#input').val($test);
)};
});
