如果单元格中的文本包含特定单词，则在其中添加图片＃2

Question

I want my table to convert specific text to images.

I came close to a solution reading this thread: If text in a cell contains a specific word then put an image in it

The problem i experience is that the table only change the first text, if example "RED" occur a 2nd time it return blank to the cell instead of another red image.

I am very novice to programming and tried copy the code from the above thread, kind of know its wrong to do the repeat like I do instead of declaring it all in same paragraph but this is how it looks now and semi-works :)

var allTableCells = document.getElementsByTagName("td");

var yourImage = new Image();
yourImage.src = "red.png";

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "RED") {
        node.textContent = "";
        node.appendChild(yourImage);
    }
}


var allTableCells = document.getElementsByTagName("td");

var yourImage = new Image();
yourImage.src = "blue.png";

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "BLUE") {
        node.textContent = "";
        node.appendChild(yourImage);
    }
}

var allTableCells = document.getElementsByTagName("td");

var yourImage = new Image();
yourImage.src = "green.png";

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "GREEN") {
        node.textContent = "";
        node.appendChild(yourImage);
    }
}

var allTableCells = document.getElementsByTagName("td");

var yourImage = new Image();
yourImage.src = "cyan.png";

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "CYAN") {
        node.textContent = "";
        node.appendChild(yourImage);
    }
}

var allTableCells = document.getElementsByTagName("td");

var yourImage = new Image();
yourImage.src = "orange.png";

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "ORANGE") {
        node.textContent = "";
        node.appendChild(yourImage);
    }
}

Really appreciate if someone could help me so each new cell that also contain the specific text get an image!

You are appending the same DOM element so you'll only end up with a single image.

Move the image element creation inside your loop

for (var i = 0;i < allTableCells.length; i++) {
    var node = allTableCells[i];
    if (node.textContent.trim() === "RED") {
        node.textContent = "";
        var yourImage = new Image();
        yourImage.src = "red.png";
        node.appendChild(yourImage);
    }
}
