assign a symbol to a module

[yawns]

getDom: function() {
	var wrapper = document.createElement("div");

	var symbol =  document.createElement("span");
	symbol.className = "fa fa-home";
	wrapper.appendChild(symbol);

	return wrapper;
}

This will result in a “house symbol”

Thanks. When i add the code, i have the “house” but i have a getdom function with the following code…

getDom: function(){
		
		var wrapper = document.createElement("div");
		if(this.dataFile){
                        var humidityRegExp = /Humidity = (.*?) %/ig;
                        var humidity = humidityRegExp.exec(this.dataFile)[1];

                        var temperatureRegExp = /Temperature = (.*?) *C/ig;
                        var temperature = temperatureRegExp.exec(this.dataFile)[1];
			wrapper.innerHTML = "r.F.: " + humidity + "%, Temp.: " + temperature + "°C";
		} else {
			wrapper.innerHTML = "No data";
		}
		return wrapper;
	},

…how do I implement the code in this?

[yawns]

like this:

getDom: function() {
	var wrapper = document.createElement("div");
	if(this.dataFile){
		var humidityRegExp = /Humidity = (.*?) %/ig;
		var humidity = humidityRegExp.exec(this.dataFile)[1];

		var temperatureRegExp = /Temperature = (.*?) *C/ig;
		var temperature = temperatureRegExp.exec(this.dataFile)[1];

		var spacer = document.createElement("span");
		spacer.innerHTML = " ";
		var temperature_symbol =  document.createElement("span");
		temperature_symbol.className = "fa fa-home";
		var humidity_symbol =  document.createElement("span");
		humidity_symbol.className = "fa fa-tint";

		wrapper.appendChild(temperature_symbol);
		var temperature_text = document.createElement("span");
		temperature_text.innerHTML = " " + temperature + "°C";
		wrapper.appendChild(temperature_text);

		wrapper.appendChild(spacer);

		wrapper.appendChild(humidity_symbol);
		var humidity_text = document.createElement("span");
		humidity_text.innerHTML = " " + humidity + "%";
		wrapper.appendChild(humidity_text);
	} else {
		wrapper.innerHTML = "No data";
	}
	return wrapper;
},

Should give you a house symbol for temperature inside and a droplet for humidity.

@yawns

I need add a symbol to text (before or behind).

Code:

getDom: function() {
		
		var header = document.createElement("header");
		var wrapper = document.createElement("div");
		if(this.config.title !== false){
			var title = document.createElement("header");
			title.innerHTML = this.config.title || this.name;
			wrapper.appendChild(title);
		}
		var logs = document.createElement("table");

		for (var i = this.messages.length - 1; i >= 0; i--) {
			//Create callWrapper
			var callWrapper = document.createElement("tr");
			callWrapper.classList.add("normal");

			
			var icon =  document.createElement("td");
			
			if (this.messages[i].type === "INFO"){
				icon.className = "fa fa-info";
			}
			else if (this.messages[i].type === "WARNING"){
				icon.className = "fa fa-exclamation";
			}
			else if (this.messages[i].type === "ERROR"){
				icon.className = "fa fa-exclamation-triangle";
			}
			else {
				icon.className = "fa fa-question";
			}
			
			
			
			//Set caller of row
			var caller =  document.createElement("td");
			caller.innerHTML = "[" + this.messages[i].type + "] " + this.messages[i].message + " " + wrapper.appendChild(icon);
			caller.classList.add("title", "small", "align-left");
			if(this.config.types.hasOwnProperty(this.messages[i].type)){
				caller.classList.add(this.config.types[this.messages[i].type]);
			}
			callWrapper.appendChild(caller);

			//Set time of row
			var time =  document.createElement("td");
			time.innerHTML = this.config.format ? moment(this.messages[i].timestamp).format(this.config.format) : moment(this.messages[i].timestamp).fromNow();
			time.classList.add("time", "light", "xsmall");
			callWrapper.appendChild(time);

			//Add to logs
			logs.appendChild(callWrapper);
		}
		wrapper.appendChild(logs);
		return wrapper;

This is effect:

What is wrong?

Hi @Plati

The solution depends on how you want to display the table.

Do you want

• 3 columns in the following order: | Icon | Message | Time |
• Or 2 columns laid out as follows: | Message Icon | Time |

[Plati]

Hi @ianperrin

| Icon | Message | Time | should be ok

[ianperrin]

@Plati said in assign a symbol to a module:

Hi @ianperrin

| Icon | Message | Time | should be ok

In that case, try this

		var iconCell = document.createElement("td");

		var icon =  document.createElement("i");
		if (this.messages[i].type === "INFO"){
			icon.className = "fa fa-info";
		}
		else if (this.messages[i].type === "WARNING"){
			icon.className = "fa fa-exclamation";
		}
		else if (this.messages[i].type === "ERROR"){
			icon.className = "fa fa-exclamation-triangle";
		}
		else {
			icon.className = "fa fa-question";
		}

		iconCell.appendChild(icon);
		callWrapper.appendChild(iconCell);
		
		//Set caller of row
		var caller =  document.createElement("td");
		caller.innerHTML = "[" + this.messages[i].type + "] " + this.messages[i].message;

[ianperrin]

You could also consider making the icon configurable via the options,

First add the default values for the options

	defaults: {
		max: 5,
		format: false,
		types: {
			INFO: "dimmed",
			WARNING: "normal",
			ERROR: "bright"
		},
		icons: {
			INFO: "info",
			WARNING: "exclamation",
			ERROR: "exclamation-triangle"
		}
	},

Then change the code to create the icon (and for bonus points, set class for the icon to the same as the message.

		var iconCell = document.createElement("td");
		var icon =  document.createElement("i");
		if(this.config.icons.hasOwnProperty(this.messages[i].type)){
			icon.classList.add("fa", "fa-" + this.config.icons[this.messages[i].type]);
		} else {
			icon.classList.add("fa", "fa-question");
		}
		if(this.config.types.hasOwnProperty(this.messages[i].type)){
			icon.classList.add(this.config.types[this.messages[i].type]);
		}
		iconCell.appendChild(icon);
		callWrapper.appendChild(iconCell);

@ianperrin nice! I still have a lot to learn. I’m just beginning to learn JS, etc.

Now is almost perfect:

Now only center the icons and reduce the spacing between the lines.

[ianperrin]

@Plati glad to help - and we’re all learning here so don’t worry!

Fontawesome provides lots of support for managing the display of icons, so if the icons are throwing the alignment in the table out try making the icons Fixed Width by adding “fa-fw” to the icon e.g. icon.classList.add("fa", "fa-fw", "fa-" …

Alternatively, set the icon font-size to the same as the message, by using the inbuilt MM styles, e.g. iconCell.classList.add("small");

or a combination of both :)
