用jquery实现的文本框只能输入数字简单插件$.fn.numeral = function() {$(this).css("ime-mode", "disabled");this.bind("keypress",function(e) { var e = e||event; var currKey = e.keyCode||e.which||e.charCode; if (currKey == 46) { if (this.value.indexOf(".") != -1) { return false; } }else { return currKey >= 46 && currKey <= 57 || currKey == 8; }});this.bind("blur", function() { if (this.value.lastIndexOf(".") == (this.value.length - 1)) { this.value = this.value.substr(0, this.value.length - 1); } else if (isNaN(this.value)) { this.value = "0"; }});this.bind("paste", function() { var s = clipboardData.getData('text'); if (!/\D/.test(s)); value = s.replace(/^0*/, ''); return false;});this.bind("dragenter", function() { return false;});this.bind("keyup", function() {if (/(^0+)/.test(this.value)) { this.value = this.value.replace(/^0*/, ''); }});};
