JavaScript 限制文本框不可输入英文单双引号

<input id="workname" style="width: 200px" name="workname" value="" type="text" onkeyup="javascript:replaceLikeVal(this)" />

正则实现replaceAll：

function replaceLikeVal(comp){
if (comp.value.indexOf("'") != -1 || comp.value.indexOf("\"") != -1) {
//comp.value = comp.value.substring(0, comp.value.length-1);
comp.value = comp.value.replace(/\'/g,"").replace(/\"/g,"");
}
}
