This class allows the client-side script executing the code on the server side using Script Includes.
To use the SimpleAjax class, complete the following steps:
- Call the SimpleAjax constructor to create a SimpleAjax instance. The script includes a name, which involves the class with the necessary methods, should be the argument for the constructor.
Call the addParam(paramName, paramValue) method.
Noteinfo When calling it, complete the following steps:
- provide sysparm_name as a parameter
- and the method name taken from the include part of the script called.
To provide other parameters to the script code, call this method as many times as you need.
- Сall the getXML(callback) method to execute the method declared above.
| Note |
|---|
The class name declared in the Script Include should match the Script Include name. To make the Script Include callable from client-side scripts, activate the Client Callable attribute. For more information and practical cases, refer to the Script Includes article. |
addParam(paramName, paramValue)
This method passes the specified parameter name and value to the server-side function associated with the current SimpleAjax object. The addParam() method can be used several times with different parameters and values.
| Note |
|---|
The server-side code runs only after getXML() is called by client script. The parameter name should start with sysparm_ prefix. Avoid using a predefined sysparm_name parameter name for passing value parameters. |
Parameter(s):
| Name | Type | Mandatory | Default value |
|---|---|---|---|
| paramName | String | Y | N |
| paramValue | String | Y | N |
Return:
| Type | Description |
|---|---|
| Void | This method does not return a value |
Example:
| Code Block | ||||||||
|---|---|---|---|---|---|---|---|---|
| ||||||||
const sAjax = new SimpleAjax('DurationCalculator'); // call script include
sAjax.addParam('sysparm_name', 'getDuration'); // call class method
sAjax.addParam('sysparm_start', s_form.getValue('start')); // pass parameter
sAjax.getXML(callback);
function callback(response) {
const answer = response.responseXML.documentElement.getAttribute('answer');
console.log(answer);
} |
getXML(callback)
By calling this method, the client script sends a request to the server where the method and parameters related to the current SimpleAjax object are executed. The request is processed asynchronously. The results will be returned via the function specified as a callback.
Return:
| Type | Description |
|---|---|
| Void | This method does not return a value. |

const sAjax = new SimpleAjax('DurationCalculator'); // call script include
sAjax.addParam('sysparm_name', 'getDuration'); // call class method
sAjax.addParam('sysparm_start', s_form.getValue('start')); // pass parameter
sAjax.getXML(callback);
function callback(response) {
const answer = response.responseXML.documentElement.getAttribute('answer');
console.log(answer);
