Supported message types

jsMessage offers 4 variations at your disposal:

  • alert
  • confirm
  • notification ( message )
  • modalbox

How to use

The type (subtype) of the message window is specified through the parameter type. The default value is "message".

    dhtmlx.message({ 
        type:"confirm-warning", 
        text:"Are you sure you want to do it?"
    })

or, you can use separate methods

    dhtmlx.confirm({
        title:"Confirm",
        text:"Continue?"
    });
    //or
    dhtmlx.alert({
        title:"Alert",
        type:"alert-error",
        text:"You can do this"
    });
    //or
    dhtmlx.modalbox({
        title:"Settings",
        text:"Abstract popup"
    }); 

Styling

For any type of the message window you can define a custom style to achieve the desired look. Generally, the appropriate css class is specified through the parameter type: you define a css class and set the parameter to its name.

    <style type="text/css">
        .dhtmlx-myCss{
            font-weight:bold !important;
            color:white !important;
            background-color:red !important;
        }
    </style>
    <script>
        dhtmlx.message({ type:"myCss", text:"some text" });
    </script>

Options

Alert

  • title - (string) the text of the header (by default, 'Alert').
  • type - the subtype of the window or a custom css class. The default value for the window - 'alert'.
  • text - (string) the text of the window body.
  • ok - (string) the text of the 'Ok' button.
  • callback - (function) the function called on button click
  • position - for now support only one value "top", any other value will result in center align
  • width - width of the modal box ( samples "100px", "50%")
  • height - height of the modal box

Full form

    dhtmlx.message({
            title: "Close",
                    type: "alert",
            text: "You can't close this window!",
            callback: function() {dhtmlx.alert("Test alert");}
    })
//or
    dhtmlx.alert({
            text: "Download is completed.",
            callback: function() {dhtmlx.alert("Test alert");}
    })

Short form

    dhtmlx.alert("someText");

Both alert and confirm blocks keyboard input while active. Pressing SPACE or ENTER will close message with positive result. Pressing ESC will close message with negative result. (you can use dhtmlx.message.keyboard = false; to disable this behavior)

Confirm

  • title - (string) the text of the header (by default, 'Alert').
  • type - the subtype of the window or a custom css class
  • text - (string) the text of the window body.
  • ok - (string) the text of the 'Ok' button.
  • cancel - (string) the text of the 'Cancel' button.
  • callback - (function) the function called on button click. Receives 'true' or 'false' as the parameter (subject to the clicked button).
  • position - for now support only one value "top", any other value will result in center align
  • width - width of the modal box ( samples "100px", "50%")
  • height - height of the modal box

Full form

    dhtmlx.message({
        type:"confirm",
        text: "Continue?",
        callback: function() {dhtmlx.confirm("Test confirm");}
    });
//or
    dhtmlx.confirm({
        title: "Close",
                type:"confirm-warning",
        text: "Are you sure you want to do it?",
        callback: function() {dhtmlx.confirm("Test confirm");}
    });

Short form

    dhtmlx.confirm("ConfirmText");

ModalBox

  • title - (string) the text of the header (by default, 'Alert').
  • type - the subtype of the window or a custom css class
  • text - (string) the text of the window body.
  • ok - (string) the text of the 'Ok' button.
  • cancel - (string) the text of the 'Cancel' button.
  • callback - (function) the function called on button click. Receives 'true' or 'false' as the parameter (subject to the clicked button).
  • buttons - array of labels, each one will be converted to the button ( much like multi-button confirm ). Callback function will receive index of pressed button ( 0 - for first button, 1 - for second button and etc. )
  • position - for now support only one value "top", any other value will result in center align
  • width - width of the modal box ( samples "100px", "50%")
  • height - height of the modal box
  • content - can be used instead of text, defines html element (or its ID) which will be shown inside of a popup

Examples

    dhtmlx.modalbox({
        title:"Settings"
        text: " ... html code here... ",
        buttons:["Save", "Defaults", "Cancel"],
        callback:process_result
    });

function returns the html container of the box which can be used for some actions

    var box = dhtmlx.modalbox(...);
    box.getElementsByTagName("input")[0].focus();
    ...
    dhtmlx.modalbox.hide(box); //hide popup  

Closing modal box

There are 3 way to close modal box

  • call dhtmlx.modalbox.hide(box) - where "box" is result of dhtmlx.modalbox command
  • call dhtmlx.modalbox.hide(node) - where node - any html node in the box (allows to create "close" links easily)
  • click on any button, which was defined through "buttons" property
    var box = dhtmlx.modalbox({
        text:"<a href='#' onclick='dhtmlx.modalbox.hide(this)'>Click to close<a>"
    });

Custom buttons

You can place a custom button in the popup, which is styled exactly as default message buttons. To do so you need to place the next html snippet

    var box = dhtmlx.modalbox({
        text:"<span class='dhtmlx_button'><input type='button' value='Press me'></span>"
    });

Content reusage

Instead of setting html text you can place any html container on the page in the modalbox

    <div id='mycontent'>Some form here </div>
    var box = dhtmlx.modalbox(content:"mycontent");

after box will be closed, you can reopen it by

    dhtmlx.modalbox(box);

Notification (message)

  • type - the subtype of the window or a custom css class. The default value for the window - 'alert'.
  • text - (string) the text of the window body.
  • expire - the time after passing which the window disappears (in milliseconds). You can use negative value (-1) to make notice persistent.

Full form

    dhtmlx.message({
        text:"An error has occured.<br /> Please, see the log file!",
        expire:1000, You can use negative value (-1) to make notice persistent. 
        type:"customCss" // 'customCss' - css class
    });

Short form

    dhtmlx.message("Your data has been successfully saved!");

Extra configuration

Default delay of notifications can be set as

    dhtmlx.message.expire = 4000; //time in milliseconds
    t.position = "top"; 

Default position of notices can be set as

    dhtmlx.message.position = "top";     // possible values "top" or "bottom"

Interaction with alert and confirm from keyboard can be disabled by

    dhtmlx.message.keyboard = false;     // possible values "top" or "bottom"

Alert subtypes

For all kinds of messages, there are alert variations, which can be used for more important notifications

    dhtmlx.message({ type:"error", "Critical error!"});
    //or
    dhtmlx.message({ type:"alert-error", "Critical error!"});
    //or
    dhtmlx.message({ type:"confirm-error", "Confirm self-destruction!"});
