How to get the value of Codemirror textarea

问题

I am using Codemirror's plugin for textarea but I am not able to retrieve the value of textarea.

Code:

var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
    lineNumbers: true,
    matchBrackets: true,
    mode: "text/x-csrc"
  });


function showCode()
{
    var text = editor.mirror.getCode();
    alert(text);
}

It is showing the error:

editor.getCode() is not a function.

回答1:

Try using getValue() instead of getCode().

Pass in an optional argument into getValue(separator) to specify the string to be used to separate lines (the default is \n).

回答2:

This works fine for me.

editor.getValue()

回答3:

use your_editor_instace.getValue();

It will work fine because there is no function named with the name as getCode() in codemirror.

for setting value use your_editor_instance.setValue();

According to the Documentation, you need now to do it like:

doc.getValue(?separator: string) → string

So in this example:

editor.getDoc().getValue("\n")

I know you are using textarea but I hope this code will be useful for others! I have this problem but with article tag, and this is my solution to getting all codes with jquery:

res_array = []
$.each($('article.code-draft span[role="presentation"]'), function(){
    res_array.push($(this).text())
});
console.log(res_array.join('\n'))
