Phone call a javascript function when a checkbox is checked unchecked
Beneath we will discuss how to create an HTML page with a checkbox and trigger issue using the onclick function.
Here nosotros are taking a small example to create an HTML page with two checkboxes to display accost when checkboxes are checked it would brandish the textbox with accost, and when unchecked it would disappear. For this instance, we have created dissever files for HTML and JavaScript files.
Create HTML Grade
You can create an HTML file using below code. Here you have two checkboxes equally Present Address and Permanent Accost with text boxes to brandish the address when clicked.
Onclick function is used to call a JavaScript function to display the Address text when checked. With text box style equally way="display:none" display visibility property as hidden.
<!DOCTYPE HTML> <html> <head> <script type="text/javascript" src="https://onlysharepoint2013.sharepoint.com/sites/Raju/SiteAssets/bibhus devlopment/developmentjava.js"></script> </head> <body id="body"> <table> <tr> <th> Address </th> <td colspan="4″> <input type="checkbox" name="Present Accost" id="chkpresent" onclick="myFunction()"> Nowadays </td> <td colspan="4″> <input type="checkbox" name="Permanent Address" id="chkpermanent" onclick="myFunction1()"> Permanent </td> </tr> <tr> <td colspan="1″></td> <td colspan="4″><input blazon ="text" id="txtpresent" style="display:none"></td> <td colspan="iv″><input type ="text" id="txtpermanent" style="display:none"></td> </tr> </table> </body> </html> And the HTML form looks similar below:
JavaScript Role
Here we have created two functions and nosotros will bind these functions to textboxes where if nosotros click the text box would appear.
Role myFunction() and role myFunction1() are the two functions and we are checking with the checkbox id which is "chkpresent " with this example of the checkbox using document.getElementById("chkpresent"); method.
If it is truthful, a text box is displayed using textbox id equally "text nowadays" and use way. brandish = " to display values if checked on else it is none. The same logic is used in the second function to display the text.
function myFunction() { var checkBox = certificate.getElementById("chkpresent"); if (checkBox.checked == true){ certificate.getElementById("txtpresent").style.display = "; } else { certificate.getElementById("txtpresent").manner.display = 'none'; } } function myFunction1() { var checkBox = certificate.getElementById("chkpermanent"); if (checkBox.checked == truthful){ certificate.getElementById("txtpermanent").mode.display = "; } else { document.getElementById("txtpermanent").fashion.display = 'none'; } } Either you tin put the above HTML and JS code inside a content editor web office or you can also use inside a script editor web function in SharePoint 2013/2016/Online.
This is how the output will appear.
Yous tin encounter text box is not visible as we have used style="brandish:none" on HTML file.
