Introduction:<\/h2>\n\n\n\n

Sometimes you might need to set a maximum number of available choices when using checkboxes.<\/p>\n\n\n\n

For example if you had eight choices and you only wanted a max of three of them accepted!<\/p>\n\n\n\n

For this purpose we will use some custom JavaScript to count how many checks are allowed.<\/p>\n\n\n\n

Using the custom page node, the script looks like this:<\/p>\n\n\n\n

<h1>Select Any Two Checkboxs<\/h1>\n<div id=\"checkboxgroup\">\n  <input type=\"checkbox\" value=\"CheckBox 1\" name=\"cbx1\"> Aubrey\n\t<input type=\"checkbox\" value=\"CheckBox 2\" name=\"cbx2\"> Laura\n\t<input type=\"checkbox\" value=\"CheckBox 3\" name=\"cbx3\"> Byron\n  \n  <!-- Note #1 Add <input type=\"checkbox\"... lines as necessary -->\n  \n<\/div>\n\n<script>\nfunction onlyOneCheckBox() {\n\tvar checkboxgroup = document.getElementById('checkboxgroup').getElementsByTagName(\"input\");\n\t\n    \/\/Note #2 Change max limit here as necessary\n    var limit = 2;\n  \n\tfor (var i = 0; i < checkboxgroup.length; i++) {\n\t\tcheckboxgroup[i].onclick = function() {\n\t\t\tvar checkedcount = 0;\n\t\t\t\tfor (var i = 0; i < checkboxgroup.length; i++) {\n\t\t\t\tcheckedcount += (checkboxgroup[i].checked) ? 1 : 0;\n\t\t\t}\n\t\t\tif (checkedcount > limit) {\n\t\t\t\tconsole.log(\"You can select maximum of \" + limit + \" checkbox.\");\n\t\t\t\talert(\"You can select maximum of \" + limit + \" checkbox.\");\n\t\t\t\tthis.checked = false;\n\t\t\t}\n\t\t}\n\t}\n}\n<\/script>\n\n<script type=\"text\/javascript\">\n\tonlyOneCheckBox()\n<\/script><\/code><\/pre>\n\n\n\n
Simply copy\/paste this code into a custom page node as is.<\/p>\n\n\n\n
And modify it as necessary. There are 2 comments to guide you. Making the process completely simple.<\/p>\n\n\n\n

Conclusion:<\/h2>\n\n\n\n
By using custom JavaScript, you can limit the number of checkboxes a user can select, providing additional control over user inputs in your decision trees.<\/p>\n","protected":false},"excerpt":{"rendered":"
