获取jQuery .filter()结果的反面/反面 [英] Get opposite/inverse of jQuery .filter() results
问题描述
我有一个 .filter
函数,它可以工作并标记< td>
输入字段为红色。
但是,我需要的是完全相反的。因此,返回所有不包含< input
的字段。
我试过 if($(this).html()。indexOf('< input')== -1){
我的jQuery:
$(document).ready (function(){
$(#ListView1_itemPlaceholderContainer table table table td)。filter(function(index){
if($(this).html()。indexOf('< input' )> 0){
return true;
}
})。closest('div')。css('background-color','red');
} );
这是我的HTML

$ b jQuery:使用filter(),但是使用两个结果。 $ b
试过这个:
< script type =text / javascript>
$ b $(document).ready(function(){
$ .fn.invert = function(){
return this.end()。not(this); $ ()($(this).html()。indexOf('b $ b};
$(#ListView1_itemPlaceholderContainer table table table td < input')> 0){
return true;
}
})。invert()。closest('div')。css('background-color','red ');
});
< / script>
但是,这也会使所有的行都变成红色。
一个href =http://api.jquery.com/has-selector/ =noreferrer>:has()
$(document:.ready(function(){
$(#ListView1_itemPlaceholderContainer table table table td)。 ).css('background-color','red');
});
I have a.filter
function, which works and marks all parents of <td>
that contain an input field in red.
However, I need the exact opposite. So return all fields that don't contain <input
.
I tried if ($(this).html().indexOf('<input') == -1) {
but that just marks all rows somehow.
My jQuery:
$(document).ready(function () {
$("#ListView1_itemPlaceholderContainer table table table td").filter(function (index) {
if ($(this).html().indexOf('<input') > 0) {
return true;
}
}).closest('div').css('background-color', 'red');
});
Here's my HTML
<div id="ListView1_itemPlaceholderContainer" style=
"font-family: Verdana, Arial, Helvetica, sans-serif;">
<div style="background-color: #FFFFFF; color: #333333;">

</div>
I also check out this post jQuery: use filter(), but work with both results as suggested by commenter.
And tried this:
<script type="text/javascript">
$(document).ready(function () {
$.fn.invert = function () {
return this.end().not(this);
};
$("#ListView1_itemPlaceholderContainer table table table td").filter(function (index) {
if ($(this).html().indexOf('<input') > 0) {
return true;
}
}).invert().closest('div').css('background-color', 'red');
});
</script>
But that also makes all rows red.
You can use .not() along with :has()
$(document).ready(function () {
$("#ListView1_itemPlaceholderContainer table table table td").not(':has(input)').closest('div').css('background-color', 'red');
});
