[英]jQuery last child selector
This is not working and I don't know why. 这不起作用,我也不知道为什么。 I have tried it in the console it works, but when I change my js codes it does not work. 我已经在控制台中尝试了它,但是当我更改我的js代码时,它不起作用。
$('#recipe-table td:last-child').width();
How can I get it the correct way? 如何获得正确的方法?
this is the html 这是HTML
<div id="div-lists">
<div id="div-recipe-table">
<table class="" id="recipe-table" cellspacing="0" cellpadding="0">
<tbody>
<tr class="recipe-list" data-ng-repeat="recipe in recipe_data" ng-click="recipe_click(recipe.CodeListe,recipe.Name)">
<td id="td-img{{recipe.CodeListe}}">
<center>
<span id="img{{recipe.ID}}X">
<a id="{{recipe.ID}}" href="javascript:void(0);">
<img ng-if="recipe.Pictures !==''" fallback-src="images/default.png" ng-src="{{recipe.Pictures}}" class="images" id="img{{recipe.ID}}"/><img ng-if="recipe.Pictures===''" class="images" src="images/default.png" id="img1"/>
</a>
</span>
</center>
</td>
<!-- I want to get The width of this <td> -->
<td class="recipes">
<div id="div-recipe-name">
<strong>{{recipe.Name}}</strong></div>
</td>
<!-- Until here
I already tried using $('.recipes').width(); but it returns 0 -->
</tr>
</tbody>
</table>
</div>
<div id="div-list-loading"></div>
<div id="div-list-noresults">{{ui_translation.UIT[171610]}}</div>
</div>
</div>
Try the following: 请尝试以下操作:
$('#recipe-table td:last').width();
From the jQuery Docs 从jQuery文档
While :last matches only a single element, :last-child can match more than one: one for each parent. :last仅匹配一个元素,而:last-child可以匹配多个:每个父元素匹配一个。
Since you have already tried $('.recipes').width();
由于您已经尝试过$('.recipes').width();
does the following provide you any results: 以下内容可为您提供任何结果:
$('.recipes').each(function (index, elem) {
alert($(this).width());
});
