我试图在$.get()
失败时显示一条简单的错误消息
$.get('{{ url_for(c) }}', function(data) {
$('#{{ chart_id }}').highcharts(data);
}).fail(function(resp) {
{# I am not sure why this is not working as intended #}
{% set error_html = error(resp, c)|replace('\n', '\\\n') %}
$('#{{ chart_id }}').html('{{ error_html }}');
});
但是,我似乎无法访问我的resp
对象,这是一个javascript变量。如何将它传递到宏中,好像它是一个字典?
答案 0 :(得分:2)
问题是Jinja在页面加载之前运行:
{# what Jinja sees #}
text ... {{ url_for(c) }} ... text ...
text ... {{ chart_id }} ... text ...
... text ...
{# I am not sure why this is not working as intended #}
{% set error_html = error(resp, c)|replace('\n', '\\\n') %}
... text ... {{ chart_id }} ... text ... {{ error_html }} ... text ...
{# What on earth is `resp`? #}
您实际上并不想在模板级别上撰写此内容 - 而是采取您的回复并在JavaScript中使用它:
.fail(function(resp) {
var displayError = calculateDisplayErrorFromResponse(resp);
$('#{{ chart_id }}').html(displayError);
});
