在一个函数中,我需要检查一个(div、span、p)是否包含任何.html元素,然后再尝试删除html并添加新内容。
不确定该如何实现...
我尝试了这个方法,但没有起作用:
// HERE below I tried to do a check to see if the div's have HTML, but did not work
if ($('.'+rowName+' div').html) {
$('.'+rowName+' div').html.remove();
$('.'+rowName+' span').html.remove();
$('.'+rowName+' p').html.remove();
}
完整功能
// Create the Role / Fan rows
function rowMaker (rowName, roleName) {
//alert(rowName+' '+roleName);
// HERE below I tried to do a check to see if the div's have HTML, but did not work
if ($('.'+rowName+' div').html) {
$('.'+rowName+' div').html.remove();
$('.'+rowName+' span').html.remove();
$('.'+rowName+' p').html.remove();
}
// Blue button
$('.'+rowName+' div').append(roleName);
$('.'+rowName+' div').attr('id', 'blue-fan-'+roleName);
var blueButton = ('blue-fan-'+roleName);
console.log('blueButton = '+blueButton);
// Genres
$('.'+rowName+' span').append(roleType);
// Tags
$.each(role_Actor, function(index, item) {
$('.'+rowName+' p').append(item+', ');
});
$('#'+blueButton).click(function () {
console.log('clicked blue button');
// clears the role_Actor to be used to recapture checkboxes
role_Actor = [];
console.log('role_Actor = '+role_Actor);
//$('#modal-'+roleId).modal();
$('#modal-'+roleId).modal({persist:true});
return false;
});
}
.html
替换整个内容呢? - Andrew Whitaker
