将鼠标焦点定位到文本框最后（代码分享）

Tinput").val("你好").focusEnd(); $.fn.setcursorPosition = function (position) { if (this.lengh == 0) return this; return $(this).setSELEction(position,position); } $.fn.setSELEction = function (SELEctionStart,SELEctionEnd) { if (this.lengh == 0) return this; input = this[0]; if (input.createTextRangE) { var range = input.createTextRange(); range.collapse(true); range.moveEnd('character',SELEctionEnd); range.moveStart('character',SELEctionStart); range.SELEct(); } else if (input.setSELEctionRangE) { input.focus(); input.setSELEctionRange(SELEctionStart,SELEctionEnd); } return this; } $.fn.focusEnd = function () { if (this.val() != undefined) { this.setcursorPosition(this.val().length); } } //设置焦点相关---end
