generating .txt file in the system directory by using the entry provided by user in field box

**hello everyone… i am new to cesium and javascript … i am developing a web application in which when user clicks on any pin billboard an iframe information box is displayed in which i have provided a HTML field box and a clickable button …now i want to create a function by using which a .txt file could be generated and saved in system using string provided by user when he clicks that button . **

**is this possible …pin’s color could be changed to another one… (eg. from blue to red) when user clicks submit button…(or a new pin could generate automatically at the same coordinate when user clicks that button…?) **

**i am using crome **
here is the sample code that i have been using

//Sandcastle_Begin

var viewer = new Cesium.Viewer(‘cesiumContainer’, {timeline : false, animation : false});

var toolbar = document.getElementById(‘toolbar’);

var pinBuilder = new Cesium.PinBuilder();

var numClicks = 0;//an variable

viewer.infoBox.frame.removeAttribute(‘sandbox’);

//viewer.selectedEntity = entity;//Gets or sets the object instance for which to display a selection indicator.

var iframe = document.getElementsByClassName(‘cesium-infoBox-iframe’)[0];

iframe.setAttribute(‘sandbox’, ‘allow-same-origin allow-scripts allow-popups allow-forms’);

viewer.infoBox.frame.sandbox = "allow-same-origin allow-top-navigation allow-pointer-lock allow-popups allow-forms ";

//}

//updateDisplay();

//function updateDisplay() {

// toolbar.innerHTML = 'Number of times you clicked either button: ’ + numClicks;

//}

//updateDisplay();

}, false);

}, false);

Hi there,

There’s a pull request [#5764] open, but not yet merged into master, that allows you to include JavaScript in an entity description. Just be aware, this has many security implications, which are discussed in that thread.

Thanks,
