选择所有复选框命令jQuery，JavaScript

Question

I'm trying to get all of my checkboxes to be checked when clicking a link

looks like this: <a href='javascript:;' onclick="$.overall.selectAll();">select all</a> <a href='javascript:;' onclick="$.overall.selectAll();">select all</a>

inputs in a loop: <input type="checkbox" name="delete[$i]" value="1" />

jquery code:

var checked_status = this.checked;

    $("input[name=delete]").each(function() {
    this.checked = checked_status;
});

Can someone help me get it to check all.. ?

When clicking at the select all link, nothing seems to happen.. (not even an error)

Answer 1

Try the following.

Updated. The handler is tied to an anchor therefore there will be no this.checked attribute available.

$("#select_all").click(function(){
    $("input[name^=delete]").attr('checked',  'checked');  
});

您将要使用[name^=delete]选择器（“开头为”），因为您的复选框名称并不完全是 “ delete”，所以它们对于某些数字X而言是“ delete [X]”。
