227 227 00:10:27,830 --> 00:10:32,650 Well, we can simply call this close model function. 228 228 00:10:32,650 --> 00:10:33,483 Right? 229 229 00:10:33,483 --> 00:10:34,840 So let's do that. 230 230 00:10:34,840 --> 00:10:37,100 Close model. 231 231 00:10:37,100 --> 00:10:40,890 And here we do actually need to call this function. 232 232 00:10:40,890 --> 00:10:44,830 Okay? Because when this function here is executing 233 233 00:10:44,830 --> 00:10:48,280 so this one here as a den reaches this line 234 234 00:10:48,280 --> 00:10:50,660 of course, something needs to happen. 235 235 00:10:50,660 --> 00:10:54,600 And what needs to happen is basically this coat. 236 236 00:10:54,600 --> 00:10:57,620 So we could just copy this coat down here 237 237 00:10:57,620 --> 00:10:59,790 but that's of course not what we want. 238 238 00:10:59,790 --> 00:11:03,820 Instead, we can simply use this function here again. 239 239 00:11:03,820 --> 00:11:06,210 And using means

Now that's of course 256 256 00:11:41,070 --> 00:11:43,020 because of this console dot log 257 257 00:11:43,020 --> 00:11:44,320 and let's get rid of this. 258 258 00:11:46,200 --> 00:11:47,160 Okay. 259 259 00:11:47,160 --> 00:11:48,090 Let's try it again, 260 260 00:11:48,090 --> 00:11:49,920 open it on this button. 261 261 00:11:49,920 --> 00:11:51,620 I hit any other key, 262 262 00:11:51,620 --> 00:11:52,780 nothing happens, 263 263 00:11:52,780 --> 00:11:56,700 I hit escape and it's gone. 264 264 00:11:56,700 --> 00:11:57,583 Great. 265 265 00:11:58,860 --> 00:12:01,190 Now let's read this code here a little bit. 266 266 00:12:01,190 --> 00:12:04,460 So basically this means if depressed key is escape 267 267 00:12:05,490 --> 00:12:09,710 and if the model does not contain the hidden class 268 268 00:12:09,710 --> 00:12:13,890 then execute disfunction to close the model. 269 269 00:12:13,890 --> 00:12:15,910 Now notice how I just said 270 270 00:12:15,910 --> 00:12:17,080 if this, 271 271 00:12:17,080 --> 00:12:19,710 and then if this, 272 272 00:12:19,710 --> 00:12:20,960 and so what I mean 273 273 00:12:20,960 --> 00:12:22,880 is that we can actually aggregate 274 274 00:12:22,880 --> 00:12:25,163 these two if statements together. 275 275 00:12:26,680 --> 00:12:30,190 And so this is the same as having just... 276 276 00:12:31,680 --> 00:12:33,500 and I'm cutting it here. 277 277 00:12:33,500 --> 00:12:36,253 So it's the same as having just this. 278 278 00:12:37,450 --> 00:12:41,110 Now we can get rid of this stuff here 279 279 00:12:42,010 --> 00:12:43,280 and that's it. 280 280 00:12:43,280 --> 00:12:46,320 And so now it reads the exact same way as before. 281 281 00:12:46,320 --> 00:12:48,173 If depressed key is escape. 282 282 00:12:49,040 --> 00:12:54,040 And if the model does not contain the class of hidden, 283 283 00:12:55,370 --> 00:12:57,053 then close the model. 284 284 00:12:58,070 --> 00:13:01,113 So give it another try just to make sure, 285 285 00:13:02,220 --> 00:13:03,950 And yes, 286 286 00:13:03,950 --> 00:13:06,000 that works perfect. 287 287 00:13:06,000 --> 00:13:07,100 Beautiful. 288 288 00:13:07,100 --> 00:13:07,933 And with this, 289 289 00:13:07,933 --> 00:13:11,060 or modal is actually feature complete. 290 290 00:13:11,060 --> 00:13:15,640 It works exactly as or demo here. 291 291 00:13:15,640 --> 00:13:17,040 And so with this, 292 292 00:13:17,040 --> 00:13:21,260 we finished this very small second project. 293 293 00:13:21,260 --> 00:13:22,093 So once again, 294 294 00:13:22,093 --> 00:13:23,990 I hope you liked this one 295 295 00:13:23,990 --> 00:13:26,090 and I hope you can start to see the power 296 296 00:13:26,090 --> 00:13:27,710 of Dom manipulation. 297 297 00:13:27,710 --> 00:13:28,860 So that in the future 298 298 00:13:28,860 --> 00:13:31,990 you will be able to build anything you can imagine just 299 299 00:13:31,990 --> 00:13:33,740 with JavaScript. 300 300 00:13:33,740 --> 00:13:36,620 Now that is of course still a long way to go, 301 301 00:13:36,620 --> 00:13:39,940 but that's also why we have the next project. 302 302 00:13:39,940 --> 00:13:42,210 Which is going to be a really nice project 303 303 00:13:42,210 --> 00:13:43,670 to basically train 304 304 00:13:43,670 --> 00:13:46,860 and reinforce most of the things that we already did 305 305 00:13:46,860 --> 00:13:49,810 in this project and to previous one. 306 306 00:13:49,810 --> 00:13:51,900 So the next project is gonna to be more 307 307 00:13:51,900 --> 00:13:53,800 like a practice project 308 308 00:13:53,800 --> 00:13:57,870 but I still believe it's very important to do that project 309 309 00:13:57,870 --> 00:13:59,460 in case you have to time. 310 310 00:13:59,460 --> 00:14:00,800 And believe me it's 311 311 00:14:00,800 --> 00:14:03,810 by far the most exciting thing we have done yet 312 312 00:14:03,810 --> 00:14:05,150 in this course. 313 313 00:14:05,150 --> 00:14:06,760 So I hope to see you there soon 314 314 00:14:06,760 --> 00:14:09,393 after you take a well deserved break. 25324
