如果文本中没有输入,我想显示弹出模式,如果根据条件有任何输入文本,我也想显示弹出模式。

我已经使用了两个模式,但它不工作。我已经使用 IF 条件根据条件显示不同的模态,但我得到了标题为“模态标题”的相同模态框。

最佳答案

不需要使用变量你需要使用$('#test').val() == ""|| $('#test').val() == null 检查条件..如果你真的想使用变量而不是你需要定义内部点击功能..工作演示如下 - : )

$('#go').click(function() {
if ($('#test').val() == "" || $('#test').val() == null ) {
$('#\\#myModal').modal('show');
}
else{
$('#\\#myModal1').modal('show');
}

});
