问题 Consider a html like below, <div id="test"> {{ sometext }} </div> <span class="testing"> {{ asdknfsdf }} </span> I want to get all the elements whose inner text matches {{ <sometext> }} in jquery.

Are you getting no results?

How to get string from several double quotes in a line?

由 自闭症网瘾萝莉.ら 提交于 2021-02-08 14:18:08

问题 I'm trying String string = "123456"; if(string.startsWith("[0-9]") && string.endsWith("[0-9]")){ //code } And the if clause is never called. 回答1: Don't use a regex: Character.isDigit(string.charAt(0)) && Character.isDigit(string.charAt(string.length()-1)) (see Character.isDigit()) 回答2: The methods startsWith() and endsWith() in class String accept only String, not a regex. 回答3: You can use: String string = "123test123"; if(string.matches("\\d.*\\d")) { // ... } 回答4: You can use the matches
