Flask中如何从后端视图函数传递多个值给前端JS
作者:互联网
背景
使用Bootstrap-table加载表格,需要从前端发起加载,从后端传递结果和Columns。
目标
实现后端向前端传递结果df(从数据库获得)和相应的Columns(用于前端展示,Field较多,不想前端Hardcoding)
方案
在后端采用字典写法,前端JS用点运算符获取即可。
后端
@app.route('/NDF/getMaintable', methods=['POST','GET'])
def getMaintable():
if session.get("user_name")==None:
return render_template("404.html")
filter_mode = request.form['filter_mode']
result = get_query_table(filter_mode)[0]
head_list = result.columns
col_dict_list = [{"field": x, "title": x, "halign": 'center', "align": "center", "sortable": 1,"width": 200} if x == "fCNName" else {"field": x, "title": x, "halign": 'center',"align": "center", "sortable": 1, "width": 100} for x in head_list]
rows = result.to_json(orient='records')
return {'rows':rows,'cols':str(col_dict_list)}
前端JS
function load(cur_status){
$.ajaxSetup({async:false})
$.post('/NDF/getMaintable', {filter_mode:cur_status}, function(data){cur_data = data})
$("#table1").bootstrapTable({
data:JSON.parse(cur_data.rows),
search: true,
singleSelect: true,
toolbar:'#toolbar',
pagination: true,
pageSize: 10,
pageList: [5, 10, 15,20,50,100],
showColumns: true,
showRefresh: true,
showToggle: true,
locale: "zh-CN",
clickToSelect:true,
stickytableheader:true,
striped: true,
method: 'get',
columns: eval(cur_data.cols)
});
}
结果
As Expected
