Replace all instances in string with a variable as the search - JavaScript

Question

I am having an issue which I cannot find documented anywhere, i see a regex method however that is using a direct string rather than string within a variable. This is my code: ``` var src = getQueryVariable("srcStr"); if(src != false){ $(".entry-content").html($(".entry-content") .html().replace(/src/g, "" + src + "")); } ``` This gets a url variable (srcStr) and searches a body of text within .entry-content for the string stored in the var `src`. The problem code is here: `replace(/src/g` Is there a solution?

Accepted Answer

You are searching for the pattern that is literally "src." You need to use the `RegExp` class if you want to use variables in patterns:

```
pattern = new RegExp(src, 'g');
$(".entry-content")...html().replace(pattern, replacement);
```
