因此,我正在为学校作业编写此代码,应该使用pygame并显示一些文本。我将这些文本放在不同的页面中,如果单击该屏幕,它将显示下一个屏幕。
这是我到目前为止所拥有的:
var newJson = '[{"firstname":{"value":"lan","condition":"EQUAL","operator":1,"type":"stringfilter","id":38}},{"firstname":{"value":"Lars","condition":"EQUAL","operator":1,"type":"stringfilter"}}]';
var addNewfilter = function (data) {
data = JSON.parse(data)
let arr = []
for (var j = 0; j < data.length; j++) {
let obj = data[j];
for (var key in obj) {
if (obj.hasOwnProperty(key)) {
var filtergroup = new $.jqx.filter();
let filter_or_operator = obj[key].operator;
let filtervalue = obj[key].value;
let filtercondition = obj[key].condition;
let filter = filtergroup.createfilter('stringfilter', filtervalue, filtercondition);
filtergroup.addfilter(filter_or_operator, filter);
$("#jqxgrid").jqxGrid('addfilter', key, filtergroup);
}
}
}
$("#jqxgrid").jqxGrid('applyfilters');
}
尽管它不起作用,但有人可以帮忙吗?谢谢!
答案 0 :(得分:2)
您一开始就定义了button = 0
,但是从不在主循环中更改其值。在drawIntro
函数中,选中if button > 0
或if button == 1
因此,显然,您永远不会执行任何if
条语句。
您需要通过调用pygame.mouse.get_pressed()
抓住鼠标按钮,并弄清楚如何正确切换到下一页。
顺便说一句,您也有3次if button == 1
,这不是我想的,因为if
语句在编写时将立即执行,因此第3页将立即显示。您需要一些计数器来跟踪下次按下鼠标按钮时需要显示的页面。

当用户按下鼠标按钮时,您需要增加button
计数器。
不应在事件循环中为每个drawIntro
调用一次pygame.MOUSEMOTION
函数,而应在主while
循环中调用一次。另外,将MOUSEMOTION
更改为MOUSEBUTTONDOWN
,以使每次点击增加一次button
。
drawIntro
函数中的条件不正确。
import pygame
pygame.init()
SIZE = (1000, 700)
screen = pygame.display.set_mode(SIZE)
clock = pygame.time.Clock()
button = 0
fontIntro = pygame.font.SysFont("Times New Roman",30)
def drawIntro(screen):
#start
if button == 0: # == 0
screen.fill((0, 0, 0))
text = fontIntro.render("Sigle click to start", 1, (255,255,255))
screen.blit(text, (300, 300, 500, 500))
elif button == 1: #page1
screen.fill((0, 0, 0))
text = fontIntro.render("page 1", True, (255, 255, 255))
screen.blit(text, (300,220,500,200))
elif button == 2: #page2
screen.fill((0, 0, 0))
text = fontIntro.render("page 2", True, (255, 255, 255))
screen.blit(text, (300,220,500,200))
elif button == 3: #page3
screen.fill((0, 0, 0))
text = fontIntro.render("page3", True, (255, 255, 255))
screen.blit(text, (200,190,500,200))
running = True
while running:
for evnt in pygame.event.get():
if evnt.type == pygame.QUIT:
running = False
if evnt.type == pygame.MOUSEBUTTONDOWN: # Once per click.
button += 1
drawIntro(screen)
pygame.display.flip()
pygame.quit()
