如何将JQuery事件绑定到具有变量ID或类的选择器? [英] How to bind JQuery event to a selector with variable id or class?

问题描述

我有一个页面，该页面可以具有可变数量的表.每个表都有一个ID和与之关联的数字(例如，table1，table2，table3). 每个表中的一列包含一个我想将click事件绑定到的链接.我有一个变量，其中包含链接选择器的ID(例如，invlink1，invlink2，invlink3).如何将此变量选择器ID绑定到事件?

I have a page that can have a variable number of tables. Each table has an id with a number associated with it (for example, table1, table2, table3). A column in each table contains a link that I want to bind a click event to. I have a variable that holds the id for the link selector (for example, invlink1, invlink2, invlink3). How do I bind this variable selector id to the event?

我目前有:

"fnDrawCallback": function(){
                            console.log('table' + $(this).attr('id'));
                            var tid = $(this).attr('id');
                            console.log(tid);
                            var tabnum = tid.slice(7,8);
                            var invoicelink = "$(\'#invlink" +tabnum+ "\')";
                            console.log(invoicelink);
                            $('[id^="rnote"]').bind('click',addreasonnote);
                            invoicelink.bind('click',viewinvoicedetails);
                            $('[id^="reason"]').bind('change',selectreasoncode);
                        },

因此，invoicelink保存选择器的ID. 我还怀疑我应该为选择器使用类而不是ID，但这不会引起语法错误.

so, invoicelink holds the id of the selector. I also suspect I should be using a class instead of an id for the selector, but that's not causing the syntax error.

推荐答案

您可以在选择器中串联一个ID字符串:

You can concatenate an ID string in the selector:

$("#" + invoicelink)...
