重建DIV id [英] Rebuild DIV id's
问题描述
我有一块输出div的php（取决于数组中的数量）并指定带有id的div（即div_1，div_2）等等。
I have a piece of php that outputs divs (depending on how many is in the array) and assigns that div with an id (i.e div_1, div_2) etc
我还设置了一个隐藏字段，其中包含输出了多少div的数量（divcount）
I also set a hidden field with the count of how many divs were outputted (divcount)
所以假设我有5个div然后div的id将是
So lets say I have 5 divs then the id's of the div's will be
- div_1，
- div_2，
- div_3
- 等等
- 并且隐藏字段（divcount）将设置为5
- div_1,
- div_2,
- div_3
- etc etc
- and the hidden field (divcount) will be set to 5
如果div_2被删除，我将divcount隐藏字段设置为4.
If div_2 gets deleted, I set the divcount hidden field to 4.
我现在需要做的是重建另一个div的id是：
What I need to do now is rebuild the other div's id's to be:
- div_1，
- div_2，
- div_3 ，
- div_4，
但目前我留下了div_1，div_3，div_4，div_5
- div_1,
- div_2,
- div_3,
- div_4, but currently I am left with div_1, div_3, div_4, div_5
我想我需要一个循环遍历每个div，并为该循环的值分配THAT div的id
I guess I need a loop to loop through each div and assign the id of THAT div the value of the loop
即
- div_1 id变为div_1
- div_3 id变为div_2
- div_4 id变为div_3
- div_5 id变为div_4
- div_1 id becomes div_1
- div_3 id becomes div_2
- div_4 id becomes div_3
- div_5 id becomes div_4
任何人都可以建议如何做到这一点吗？
Can anyone advise on how to do this?
谢谢提前！
推荐答案
您可以使用每个方法。
$('div[id^="div_"]').each(function(i){
this.id = 'div_'+(++i)
})
