Lot of times user needs to enter data quickly. \u00a0In this case we would like to share with you how we have built a custom screen to enter Order Lines data quickly. But we had a unique requirement is that wherein when the user enters ENTER <\/strong>keyword, control needs to go to next line on same field. <\/p>\n\n\n\n

We built this screen in Lightning Web Component (LWC) but there is no direct event to catch keypress for lightning-input. As a workaround we have used below code to listen ENTER <\/strong>key.<\/p>\n\n\n\n

span onkeypress={key_event}>\r\n    <lightning-input id=\"Input_Id\" label=\"Enter\" \r\n                         type=\"text\" onchange={Test_Event}>\r\n    <\/lightning-input>\r\n<\/span>\r<\/code><\/pre>\n\n\n\n
Here we have added HTML <span> element across lightning-input\u00a0to catch the keypress event. Since span is standard HTML element and have inbuilt keypress event so we have utilized same in our code. <\/p>\n\n\n\n
Below code is for JS file<\/p>\n\n\n\n
Key_event (component, event, helper) {\r\n        if (component.which == 13) {\r\n            alert (Perform some action ');\r\n       }\r\n   }<\/code><\/pre>\n\n\n\n
Here we have used component.which <\/strong>property to identify the key code. Likewise, you can use component.which <\/strong>property to identify the key codes.<\/p>\n\n\n\n
You can find all key code at the web site http:\/\/gcctech.org\/csc\/javascript\/javascript_keycodes.htm<\/a><\/strong><\/em><\/p>\n\n\n\n
Using the details mentioned in the blog we hope you are able to make use of the keypress event for capturing the details. <\/p>\n\n\n\n
