## Parameters
@ -13,7 +13,8 @@ In addition to the [parameters available in all plugins](../overview/plugins.md#
| text | string | *undefined* | The cloze text to be displayed. Blanks are indicated by %% signs and automatically replaced by input fields. If there is a correct answer you want the system to check against, it must be typed between the two percentage signs (i.e. % correct solution %). |
| button_text | string | OK | Text of the button participants have to press for finishing the cloze test. |
| check_answers | boolean | false | Boolean value indicating if the answers given by participants should be compared against a correct solution given in the text (between % signs) after the button was clicked. If ```true```, answers are checked and in case of differences, the ```mistake_fn``` is called. In this case, the trial does not automatically finish. If ```false```, no checks are performed and the trial automatically ends when clicking the button. |
| mistake_fn | function | ```function(){}``` | Function called if ```check_answers``` is set to ```true``` and there is a difference between the participants answers and the correct solution provided in the text. |
| allow_blanks | boolean | true | Boolean value indicating if the answers given by participants should be checked for completion after the button was clicked. If ```true```, answers are not checked for completion and blank answers are allowed. The trial will then automatically finish upon the clicking the button. If ```false```, answers are checked for completion, and in case there are some fields with missing answers, the ```mistake_fn``` is called. In this case, the trial does not automatically finish. |
| mistake_fn | function | ```function(){}``` | Function called if ```check_answers``` is set to ```true``` or ```allow_blanks``` is set to false and there is a difference between the participants answers and the correct solution provided in the text, or if there is at least one field with a blank answer respectively. |
