Unlike Deluge Custom Functions that run server-side, ClientScript runs client-side, allowing real-time field validation, dynamic UI changes, and front-end automation as users interact with records.<\/div>\n<div class=\"gt-section\">\n<h2>What ClientScript Can Do<\/h2>\n<p>ClientScript listens to page events: <code>onLoad<\/code> (when a record page opens), <code>onChange<\/code> (when a field value changes), and <code>onSave<\/code> (before a record is saved). In response to these events, it can: show or hide fields based on other field values, populate fields automatically from related record data, validate field values before save and block the save if validation fails, fetch data from external APIs and display it on the record, and update field values dynamically as the user types.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>ClientScript vs Layout Rules vs Deluge<\/h2>\n<p><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/layout-rule\/\" class=\"sp-content-link\">Layout Rules<\/a> handle simple show\/hide based on picklist values with no coding. ClientScript handles complex front-end logic with JavaScript and API calls. <a href=\"https:\/\/aaxonix.com\/resources\/glossary\/deluge-scripting\/\" class=\"sp-content-link\">Deluge Custom Functions<\/a> handle server-side automation triggered by workflow events. All three can be combined in a single CRM implementation.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Industry Example<\/h2>\n<div class=\"gt-example-box\"><strong>Healthcare Equipment Sales:<\/strong> A medical device company uses ClientScript on the Deals module. When the &#8220;Equipment Model&#8221; field changes, a ClientScript onChange handler automatically fetches the equipment&#8217;s standard price from a custom Products module via the Zoho CRM API and pre-fills the &#8220;List Price&#8221; field. It also validates that the entered discount does not exceed the model-specific maximum, showing an inline error before the rep even tries to save the record.<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Related Terms<\/h2>\n<div class=\"gt-related-pills\"><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/deluge-scripting\/\" class=\"sp-content-link gt-related-pill\">Deluge Scripting<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/layout-rule\/\" class=\"sp-content-link gt-related-pill\">Layout Rule<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/page-layout\/\" class=\"sp-content-link gt-related-pill\">Page Layout<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/custom-function-workflow-action\/\" class=\"sp-content-link gt-related-pill\">Custom Function (Workflow Action)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/kiosk-studio\/\" class=\"sp-content-link gt-related-pill\">Kiosk Studio<\/a>\n<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"gt-faq-item\">\n<h3>What is ClientScript in Zoho CRM?<\/h3>\n<p>ClientScript is a JavaScript framework in Zoho CRM that runs in the browser and responds to front-end events like field changes and page loads.
