在Jquery中获取Span id属性值 [英] Getting the Span id attribute Value in Jquery

问题描述

我有一个"mytable"，其中包含"mytd"，反过来又包含我要获取的"Myspan" 我想在jquery中获取"myspan_1".我该怎么做.

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.

小尝试在这里

$("#mytable").find('td > #span').attr("value","myspan_+i");

其中"i"是递增值

我无法获得Span ID.所有iam都尝试使用span标签的"id"值

I coud not get Span id .All iam trying "id" value of span tag

推荐答案

尝试这些

$("#mytable").find("td > span").attr("id");

这将获得当前跨度的id.如果要为跨度指定id，则可以执行此操作.

this will get the id of the current span. if you want to assign an id to the span you can do this.

$("#mytable").find("td > span").attr("id", "myspan_"+i");

其中i是增量变量.

此外，如果要向每个td > span添加ID，则可以在#mytable的所有td中执行for循环或$.each()

furthermore, if you are adding id to each td > span you can do a for loop or $.each() in all td of #mytable

var i=0;
$.each($("#mytable").find("td"), function(){
    $(this).find("span").attr("id", "myspan_"+i);
    i++;
});

当我阅读你的书名时，我想我想念了你的问题.但我认为这就是您想要的.实际上，如果要在jquery中查找id，则要在id为#span的元素中获取属性Value的值，因为id始终是唯一的，因此可以直接调用它. >

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 Value in the element with id of #span actually if you are looking for an id in jquery, you can call it directly since id is always unique.

$("#span").attr("value", "myspan_"+i);

由于i是一个增量值，因此需要将其放在引号之外.

since i is an incremental value, you need to put it outside the quotes.

为属性添加值value

$("#mytable").find("td > #span").attr("value", "myspan_"+i);

假设您的span id具有增量myspan_1，该增量总是从1开始

Edit 3:

Assuming your span id has an incremental myspan_1 which always starts at 1

var spanid = $("#mytable").find("td > span").attr("id", "myspan_"+i);
var idvalue = spanid.split('_')[1];

这将获得myspan_1中的1

this will get the 1 of the myspan_1

或者您可以直接获得i，因为i是您想要的号码

or you could just directly get the i since i is the number that you want

var spanid = $("#mytable").find("td > span").attr("id", "myspan_"+i);
var idvalue = i;
