For a regular expression matching, even double quotation marks, the

If a string starts with #, ending with # No.
#str = str1 + "test";# //To match the success of
#str = "test" + str1 + "test";# //This can be matched successfully
#str = "test + str1";# //To match the success of
#str = "te"st" + str1;# //Can't match the success

As in the example above, there are no heroes to help write a regular expression, that is to match a string, which contain only even quotes. Quotation of the position is uncertain, as long as the number inside quotation marks is even on the line

Seeking advice, for discussion.

Come ah, I also give points~

The 1 end is # No.,
2 even Quotes

var str = '#str = "test" + str1 + "test";#';
if(str.match(/^#.+#$/) && str.match(/\"/g).length%2 === 0) {

Dear, oh oh... All I want is a regular expression, used for string matching, I was not know the contents of the string.

IndexOf and lastIndexOf detection'#'Is it right? In 0 position and the str.length-1 position
match(/\"/g)Array elements are measured Is it right? Even
Try it
Do not know the contents of a string like ah

LZ, what the hell are you talking about? I don't know where STR is the content of the ah, don't I know? What?? The first line of the VaR STR? Tears ran ah ~ ~ ~ to me what to say?

Like the following dialogue:

A: How to calculate the obesity index ah, I want a formula.
B: Set the height h, weight W (m) (kg) for example, h=1.8, w=90, =w index/(h*h)=90/(1.8*1.8)=27.78
A: Oh dear, no, I do not know in advance of height and weight, all I want is a formula, then calculate
B: Speechless + tears

May be I did not say clearly, I is a short string above conditions from a string to find the fit, I want to find its location, and then to replace it. Say from A to Z traversal, I don't know this string in which position, do not know how long. All I need is a regular expression to match search, using regular expressions.
For example: matching Tencent QQ number: [1-9][0-9]{4,} like this.
Dear, you this is whether a string meets 1 end is #, containing 2 even conditions of the two quotation marks, and not find

With the upstairs, thank you~

Dear, you are a building problem really misleading.

A bit long winded, (some non quotes + quotes several non quotes quotes + + + some non quotes) repeat
Or: /#(([^"]*"[^"]*){2})+#/
Here are some details, such as # "" "" "" #, # #, ##, these extreme want, you see, the difference is * and +.

I am a man, don't dear to me.
This problem, by regular failed.
To write a function.

If you are female.

Thank you ~ problem has been solved, according to what you said, actually very simple also, I think the question is not so thorough ~ learning.

function check(str){
alert(/#.+=("[^"]+"|[^"+]+)((\+{1}"[^"]+")|(\+{1}[^"+]+))*;#/g.test(str.replace(" ","")));
