复杂的jquery选择器:挑战

发布于 2024-10-14 08:23:25 字数 1484 浏览 5 评论 0原文

我已经在 jquery 选择器 中搜索了一段时间,但找不到任何解决方案我的问题。

我有一个由 foreach 归档的 html 表。每行都有几个弹出工具提示的链接。我的问题:找不到正确的选择器。

<table>
    <?php foreach($article) :?>
    <tr>
        <td>
            <div class="none" style="display:none;">
                <div class="tooltip_1">
                    "The content of my tooltip_1"
                </div>
                <div class="tooltip_2">
                    "The content of my tooltip_2"
                </div>
            </div>
            <div class="cell">
                <a href="#" class="link_to_tooltip_1">a link</a>
                <a href="#" class="link_to_tooltip_2">a link</a>
            </div>
        </td>
    <tr>
    <?php endforeach; ?>
</table>

为了显示我的工具提示,我使用 qTip,它的工作原理如下:

$('a[class="link_to_tooltip_1"]').qtip({
    content: $('jquery selector'),
    (... other options)
});

所以基本上,我会需要类似的东西

content: $('self.parentNode.parentNode > div[class="none"] > div[class="tooltip_1"]'),

  • 从链接“link_to_tooltip_1”开始,
  • 返回父div“cell”,
  • 返回父td,
  • 然后转到子div“none”
  • ,最后选择子div“tooltip_1”,

非常感谢。

I've searched among jquery selectors for some time now, but can't find any solution to my problem.

I've got an html table filed by a foreach. On each line, several links that pop up tooltips. My problem : can't find the right selector.

<table>
    <?php foreach($article) :?>
    <tr>
        <td>
            <div class="none" style="display:none;">
                <div class="tooltip_1">
                    "The content of my tooltip_1"
                </div>
                <div class="tooltip_2">
                    "The content of my tooltip_2"
                </div>
            </div>
            <div class="cell">
                <a href="#" class="link_to_tooltip_1">a link</a>
                <a href="#" class="link_to_tooltip_2">a link</a>
            </div>
        </td>
    <tr>
    <?php endforeach; ?>
</table>

To show my tooltip, I use qTip, and it works like this :

$('a[class="link_to_tooltip_1"]').qtip({
    content: $('jquery selector'),
    (... other options)
});

So basicaly, I would need something like

content: $('self.parentNode.parentNode > div[class="none"] > div[class="tooltip_1"]'),

in other words :

  • start from link "link_to_tooltip_1"
  • go back to parent div "cell"
  • go back to parent td
  • then go to child div "none"
  • and finally select child div "tooltip_1"

Thanks a lot.

// this is "complex" version;
// assumes .cell and .none are nested inside same container, whether <td> or <li> or anything
$(".link_to_tooltip_1").each(function () {
    console.log($(this).closest(".cell").siblings(".none").find(".tooltip_1"));
    // $(this).qtip({ content: /* use above selector */ });
});

// this is the "not-so-complex" version;
// assumes both items are nested arbitrary level deep inside same <td>
$(".link_to_tooltip_1").each(function () {
    console.log($(this).closest("td").find(".tooltip_1"));
    // $(this).qtip({ content: /* use above selector */ });

$('a.link_to_tooltip1').closest('tr').find('.tooltip_1');

可能是您正在寻找的?

$('a.link_to_tooltip1').closest('tr').find('.tooltip_1');

is probably what you're seeking for ?

为什么不这样放置你的工具提示呢? :

<table>
    <?php foreach($article) :?>
    <tr>
        <td>
            <div class="cell">
                <span class="tooltip_1" style="display:none;" >"The content of my tooltip_1"</span><a href="#" class="link_to_tooltip_1">a link</a>
                <span class="tooltip_2" style="display:none;" >"The content of my tooltip_2"</span><a href="#" class="link_to_tooltip_2">a link</a>
            </div>
        </td>
    <tr>
    <?php endforeach; ?>
</table>

$('a[class="link_to_tooltip_1"]').qtip({
    content: $(this).children("span"),
    (... other options)
});

编辑
我不知道你不能使用 $(this)。所以在这种情况下,你可以这样做:

$('a[class="link_to_tooltip_1"]').each(function(){
    var content = $(this).prev("span");
    $(this).qtip({
    content: content,
    (... other options)
});

why not place your tooltip like this ? :

<table>
    <?php foreach($article) :?>
    <tr>
        <td>
            <div class="cell">
                <span class="tooltip_1" style="display:none;" >"The content of my tooltip_1"</span><a href="#" class="link_to_tooltip_1">a link</a>
                <span class="tooltip_2" style="display:none;" >"The content of my tooltip_2"</span><a href="#" class="link_to_tooltip_2">a link</a>
            </div>
        </td>
    <tr>
    <?php endforeach; ?>
</table>

and

$('a[class="link_to_tooltip_1"]').qtip({
    content: $(this).children("span"),
    (... other options)
});

Edit
I didn't know you can't use $(this). So in this context, you can do :

$('a[class="link_to_tooltip_1"]').each(function(){
    var content = $(this).prev("span");
    $(this).qtip({
    content: content,
    (... other options)
});

这是您正在寻找的选择器:

"td:has(.cell .link_to_tooltip_1) .none .tooltip_1"

说明:

您不能向后(匹配一个元素,然后匹配其父元素)。但是,您可以选择一个元素并验证它是否包含与其他选择器匹配的元素

"td:has(.cell .link_to_tooltip_1)"

这会选择.link_to_tooltip_1 的父级 。因此,这正是您所描述的 .link_to_tooltip_1.parentNode.parentNode

然后,您只需在选定的 中选择 .none .tooltip_1

"td:has(.cell .link_to_tooltip_1) .none .tooltip_1"

因此您的示例代码变为:

$('a[class="link_to_tooltip_1"]').qtip({
    content: $("td:has(.cell .link_to_tooltip_1) .none .tooltip_1"),
    (... other options)
});

正如您所要求的,这只需完成即可一个 jquery 选择器:-)

Here is the selector you are looking for:

"td:has(.cell .link_to_tooltip_1) .none .tooltip_1"

Explanations:

You can't go backwards (match an element, and then its parent). However you can select an element and verify that it contains elements that match an other selector:

"td:has(.cell .link_to_tooltip_1)"

This selects the parent <td> of .link_to_tooltip_1. So this does exactly the .link_to_tooltip_1.parentNode.parentNode you described.

Then you just have to select .none .tooltip_1 in the selected <td>:

"td:has(.cell .link_to_tooltip_1) .none .tooltip_1"

So your example code becomes:

$('a[class="link_to_tooltip_1"]').qtip({
    content: $("td:has(.cell .link_to_tooltip_1) .none .tooltip_1"),
    (... other options)
});

And as you were asking for, this is done with just a jquery selector :-)

我会尝试这样的事情:

使用工具提示和 rel 属性向元素添加一个类,其中包含保存数据的元素的目标类,

<a href="#" class="iHaveATooltip" rel="tooltip1">link with tooltip yar!</a>

然后在 JS 中,

$('a.iHaveATooltip').bind('mouseenter', function(){ 
    $(this).addClass('showingTooltip'); 
}).bind('mouseleave', function(){ 
    $(this).removeClass('showingTooltip'); 
}).qtip({
    content: function(){ return $('.' + $('.showingTooltip').attr('rel')).html() },
    (... other options)
});

这是我可以用来欺骗缺乏对基于通用数据引用的支持的唯一想法DOM 结构。虽然不能保证它会起作用,因为我不知道该插件,也不知道将函数作为参数传递是否不会与它的实现方式发生冲突 - 您可能必须更改插件以允许它接受函数内容参数。

再见,祝你好运,

汤姆

I'd try something like this:

add a class to the elements with tooltips and rel attribute with the target class of element holding data

<a href="#" class="iHaveATooltip" rel="tooltip1">link with tooltip yar!</a>

then in JS

$('a.iHaveATooltip').bind('mouseenter', function(){ 
    $(this).addClass('showingTooltip'); 
}).bind('mouseleave', function(){ 
    $(this).removeClass('showingTooltip'); 
}).qtip({
    content: function(){ return $('.' + $('.showingTooltip').attr('rel')).html() },
    (... other options)
});

it's the only idea I can come with to cheat the lack of support for generic data referencing based on DOM structure. Though can't promise it will work as I don't know the plugin and don't know if passing function as an argument won't collide with how it's implemented - you might have to change the plugin to allow it to accept function as content parameter.

good bye and good luck,

Tom
