/*------------------------------------------------------------------------------\ | Form Validation Installation and Samples | |-------------------------------------------------------------------------------| | | | ***************************** INSTALLATION ****************************** | | 1. Include validation.js in your HTML-file: | | | | | | 2. Insert the following code in your -section: | | | | | | header: The message in the dialogbox with DTF label | | name: The field's name in the form (Required) | | type: (string, num, email) (Required) | | ErrorMessage: The error message shown in the dialogbox (Required) | | min: [minimum num. of characters,null] (Optional) | | max: [maximum num. of characters,null] (Optional) | | | | 3. Insert an "onLoad" in your -tag: | | | | | | 4. Insert an "onSubmit" inside your

-tag: | | | | | | ************************************************************************* | | | | ******************************* SAMPLES ********************************* | | function init(){ | | formValidate('arrival','string','<%=objLabels.strGetLabel(9026)%>'); | | formValidate('children','num','<%=objLabels.strGetLabel(9008)%>'); | | formValidate('phone','string','<%=objLabels.strGetLabel(9014)%>',8,16); | | } | | ************************************************************************* | | | \------------------------------------------------------------------------------*/ var checkObjects = new Array(); // Array containing the objects to validate. var errors = ""; // Variable holding the error message. var returnVal = false; // General return value.
