当我点击ADD按钮时,它应该将所有html添加到textarea中,并且工作正常。但是,如果我再次单击,我应该从文本区域中删除它。 一个想法可能是将插入的html推入数组?
$('body').on('click', '.btn_video', function() {
var $imageSelected = $(this).parent().parent().parent().prop('outerHTML');
$('#usp-custom-5').val(function(_, currentValue) {
return currentValue + $imageSelected
});
});

<textarea name="usp-custom-5" id="usp-custom-5" data-required="false" placeholder="Example Input 5" data-richtext="false" class="usp-input usp-textarea usp-form-16" rows="5" cols="30" style="margin: 0px; height: 266px; width: 996px;"></textarea>
$('body').on('click', '.btn_video', function() {
var $imageSelected = $(this).parent().parent().parent().prop('outerHTML');
$('#usp-custom-5').val(function(_, currentValue) {
return currentValue + $imageSelected
});
});

看看它是否是你需要的:
return $imageSelected
取代:
var arr = [];
$('body').on('click', '.btn_video', function() {
var $imageSelected = $(this).parent().parent().parent().prop('outerHTML');
$('#usp-custom-5').val(function(_, currentValue) {
arr.push($imageSelected);
return $imageSelected
});
});
如果您需要在删除之前保存信息,请粘贴一个数组:
{{1}}

您可以为此使用帮助程序类selected
,然后单击添加/删除它:
$('body').on('click', '.btn_video', function() {
var content = "";
if($(this).text()=="ADD")
{
$(this).text("REMOVE");
$(this).parents(".thumbnail").parent().addClass('selected');
}else{
$(this).text("ADD");
$(this).parents(".thumbnail").parent().removeClass('selected');
}
$('.selected').each(function(){
content += $(this).prop('outerHTML');
});
$('#usp-custom-5').val(content);
});
希望这有帮助。
