我正在尝试从一组未选中的values
复选框中存储html
。我知道JQuery
没有:unchecked选择器,所以我必须反转:checked选择器。我已经完成此操作,并且得到了未选中框的值以及许多其他值,例如null
和0
。我不知道这些来自哪里。
这是我的HTML
:
<div id="tag_results">
<ul>
<li>
<input type="checkbox" value="29" name="tag" checked=""></input>
Agriculture
</li>
<li>
<input type="checkbox" value="30" name="tag" checked=""></input>
Angling
</li>
<li>
<input type="checkbox" value="37" name="tag"></input>
Animals
</li>
<li>
<input type="checkbox" value="54" name="tag" checked=""></input>
Arts
</li>
</ul>
</div>
这是我的
JQuery
: $('#saveBtn').click(function(e){
e.preventDefault();
//Get hidden field values and store in an Array
$tagArray = [];
$removeTags = [];
//Get the Checked Tags and store in an Array(will be added)
$('#tag_results :checked').each(function(){
$tagArray.push(this.value);
});
//Get the Unchecked Tags and Store in an Array(will be removed)
$('#tag_results :not(:checked)').each(function(){
$removeTags.push(this.value);
});
console.log($removeTags);
//Make Ajax request to the add_tags script and pass Array as parameter. When response recieved show dialog.
//Pass the name, id and type of company with the array of tags to the save_tags.php script.
$('#active_tags').load('pages/ajax/save_tags.php', {'removeTags': JSON.stringify($removeTags),'tags': JSON.stringify($tagArray) ,'name': $('#comp_name').val(), 'id': $('#comp_id').val(), 'type': $('#type').val() }, function(response, status, xhr){
});
});
这是
console.log
的结果:Array [ undefined, 0, 0, 0, "37", 0, "54" ]
这是我用来为复选框生成
html
的代码:$output = "<ul>";
if(mysql_num_rows($result) > 0){//If results returned (tags found matching letter) so construct list
while($row = mysql_fetch_array($result)){//while there are rows in the results array add a list item
if(in_array($row['name'], $applied_tags)){
$output .= "<li>" .'<input checked type="checkbox" name="tag" value="'.$row['id'].'">' .$row['name'] .'</li>'.PHP_EOL;
}else{
$output .= "<li>" .'<input type="checkbox" name="tag" value="'.$row['id'].'">' .$row['name'] .'</li>'.PHP_EOL;
}
}
}else{//Else there was no matching tags so display an error message to the user.
$output .= "<li>No Tags found beginning with the letter " . $letter . "</li>";
}
$output .= "</ul>";
有谁知道这可能是什么原因吗?根据上面的代码,数组肯定应该包含值37和54 ...
最佳答案
试试看
$("input:checkbox:not(:checked)")
