IE，手機都好使
谷歌和360不執行
程序是點擊選擇材料--選擇“金”---在型號里應彈出4135 4140 4340。但谷歌和360彈不出來。
哪的病呢？

把這些代碼洗掉，這些沒什么用

回2樓 洗掉也不行uj5u.com熱心網友回復：
這段代碼是想做什么？邏輯通嗎？if (inForm.material.options[0].value == '') {
inForm.material.options[0] = null;
if (navigator.appName == 'Netscape') {
if (parseInt(navigator.appVersion) < 4) {
window.history.go(0);
}
else {
if (navigator.platform == 'Win32' || navigator.platform == 'Win16') {
window.history.go(0);
}
}
}
}
