Flask的模板语言是按Jinja2模板语言的标准，基于jinja2做了一点点的封装
1.使用STUDENT字典传递到前端
后端:
@app.route("/student") def index(): return render_template("student.html", student=STUDENT)
前端:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>student information manage</title> </head> <body> <div>{{ student }}</div> <table border="1px"> <tr> <td>{{ student.name }}</td> <td>{{ student["age"] }}</td> <td>{{ student.get("gender") }}</td> </tr> </table> </body> </html>
2. STUDENT_LIST 列表传入前端Jinja2 模板的操作
后端:
@app.route("/student_list") def student_list(): return render_template("student_list.html", student=STUDENT_LIST)
前端:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>student information manage</title> </head> <body> <div>{{ student }}</div> <table border="1xp"> {% for foo in student %} <tr> <td>{{ foo }}</td> <td>{{ foo.name }}</td> <td>{{ foo.get("age") }}</td> <td>{{ foo["gender"] }}</td> </tr> {% endfor %} </table> </body> </html>
3.STUDENT_DICT 大字典传入前端 Jinja2 模板
后端:
@app.route("/student_dict") def student_dict(): return render_template("student_dict.html", student=STUDENT_DICT)
前端:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>student information manage</title> </head> <body> <table> {% for foo in student %} <tr> <td>{{ foo }}</td> <td>{{ student.get(foo).name }}</td> <td>{{ student[foo].get("age") }}</td> <td>{{ student[foo]["gender"] }}</td> </tr> {% endfor %} </table> </body> </html>
在遍历字典的时候,foo 其实是相当于拿出了字典中的Key
4.结合所有的字符串儿全部专递前端Jinja2 模板
后端:
@app.route("/allstudent") def all_student(): return render_template("all_student.html", student=STUDENT , student_list = STUDENT_LIST, student_dict= STUDENT_DICT)
前端:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>student information manage</title> </head> <body> <div>{{ student }}</div> <table border="1px"> <tr> <td>{{ student.name }}</td> <td>{{ student["age"] }}</td> <td>{{ student.get("gender") }}</td> </tr> </table> <hr> <div>{{ student_list }}</div> <table border="1xp"> {% for foo in student_list %} <tr> <td>{{ foo }}</td> <td>{{ foo.name }}</td> <td>{{ foo.get("age") }}</td> <td>{{ foo["gender"] }}</td> </tr> {% endfor %} </table> <hr> <div>{{ student_dict }}</div> <table border="1xp"> {% for foo in student_dict %} <tr> <td>{{ foo }}</td> <td>{{ student_dict.get(foo).name }}</td> <td>{{ student_dict[foo].get("age") }}</td> <td>{{ student_dict[foo]["gender"] }}</td> </tr> {% endfor %} </table> </body> </html>
