提问by Someone
I have a "mytable" which contains "mytd" inturn contains the "Myspan" i want to get the .I want to get the "myspan_1" in jquery .How do i do that.
我有一个包含“mytd”的“mytable”反过来包含我想要获取的“Myspan”。我想在 jquery 中获取“myspan_1”。我该怎么做。
Small try here
小尝试这里
$("#mytable").find('td > #span').attr("value","myspan_+i");
where "i" is an incrementing value
其中“i”是一个递增的值
I coud not get Span id .All iam trying "id" value of span tag
我无法获得 Span id 。我正在尝试 span 标签的“id”值
回答by rob waminal
try these
试试这些
$("#mytable").find("td > span").attr("id");
this will get the idof the current span. if you want to assign an idto the span you can do this.
这将获得id当前跨度的 。如果你想为id跨度分配一个，你可以这样做。
$("#mytable").find("td > span").attr("id", "myspan_"+i");
where iis an incremental variable.
其中i是增量变量。
furthermore, if you are adding id to each td > spanyou can do a for loop or $.each()in all td of #mytable
此外，如果您要为每个添加 id，则td > span可以执行 for 循环或$.each()在所有 td 中#mytable
var i=0;
$.each($("#mytable").find("td"), function(){
$(this).find("span").attr("id", "myspan_"+i);
i++;
});

As I read your title i think I miss understood your question. But I think here's what you want. You want to get the value of the attribute Valuein the element with id of #spanactually if you are looking for an idin jquery, you can call it directly since idis always unique.
当我阅读您的标题时，我想我想念您的问题。但我认为这就是你想要的。如果您在 jquery中寻找一个，您想获取Value元素中 id属性的值，您可以直接调用它，因为它始终是唯一的。#spanidid
$("#span").attr("value", "myspan_"+i);
since iis an incremental value, you need to put it outside the quotes.
由于i是增量值，因此您需要将其放在引号之外。

To add value to an attribute value
为属性添加值 value
$("#mytable").find("td > #span").attr("value", "myspan_"+i);

Assuming your span idhas an incremental myspan_1which always starts at 1
假设您span id有一个myspan_1始终从 1 开始的增量
var spanid = $("#mytable").find("td > span").attr("id", "myspan_"+i);
var idvalue = spanid.split('_')[1];
this will get the 1 of the myspan_1
这将获得 myspan_1 的 1
or you could just directly get the isince iis the number that you want
或者你可以直接得到i因为i是你想要的数字
var spanid = $("#mytable").find("td > span").attr("id", "myspan_"+i);
var idvalue = i;
