提问by DEVOPS
I have to get all the image tags ids inside a particular div. How can I get that using JQuery?
我必须在特定 div 中获取所有图像标签 ID。我怎样才能使用 JQuery 得到它?
回答by Reigel
var arraysOfIds = $('#particularDivId img').map(function(){
return this.id;
}).get();
// arraysOfIds has now all the id's, access it as arraysOfIds[0], arraysOfIds[1]....

Rough guess, but try:
粗略猜测,但请尝试:
var imgIds = new Array();
$("div#divID img").each(function(){
imgIds.push($(this).attr('id'));
});
You haven't given the name of the div
, but I've used divId
as the id of the div. Simply change that to suite your needs.
您没有给出 的名称div
,但我已将其用作divId
div 的 id。只需更改它即可满足您的需求。

Use a child selector. So your saying I want all of the child 'img' elements of div #myDiv
使用子选择器。所以你说我想要 div #myDiv 的所有子“img”元素
$("#myDiv > img").css("border", "3px double red");

function textOnly() {
jQuery('#dvContent img').each(function () {
jQuery(this).css('display', 'none');
});
}
