Try this RegEx : ng-pattern="/^(?!0+$)\d{10}$/" using look-ahead.

Use javascript match().

if (!myString.match(/(0*[1-9]+0*)+/) {
    alert("Invalid string!");
};

The above requires the input to have at least one non-zero number. Here's a fiddle to demonstrate with ng-pattern as requested:

<input ng-model="myText" ng-pattern="/^(0*[1-9]+0*)+$/" type="text" />

It is better to put regex in your controller $scope variable, and bind it inside ng-patter.SEE THIS

 $scope.regex = /([0]+[1-9]+[0]+)?$/;
    ng-pattern="regex";

OR,

ng-pattern="^([0]+[1-9]+[0]+)?$"

You could use a regEx pattern that checks if the input contains at least one number:

ng-pattern=".*[0-9].*"

RegEx is from Regular Expression For At Least One Number
