Format input wang

Terdapat empat perwakilan wang yang kami boleh terima: "10000.00" dan "10,000.00", dan "10000" dan "10,000" tanpa "sen": <span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^[1-9][0-9]*$</span>^[1- 9][0 -9]*$

🎜

Ini bermakna sebarang nombor yang tidak bermula dengan 0. Walau bagaimanapun, ia juga bermakna aksara "0" tidak diluluskan, jadi kami menggunakan borang berikut: <code mp-original-font-size="14.449999809265137" mp-original-line-height="23" style="margin: 0px 0.15em;padding: 0px 0.3em;outline: 0px;max-width: 100%;font-size: 14.45px;font-family: Consolas, Inconsolata, Courier, monospace;white-space: pre-wrap;border-width: 1px;border-style: solid;border-color: rgb(234, 234, 234);background-color: rgb(248, 248, 248);border-radius: 3px;display: inline;line-height: 23px;box-sizing: border-box !important;overflow-wrap: break-word !important;"><span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^(0|[1-9][0-9]*)$</span>

一个0或者一个不以0开头的数字.我们还可以允许开头有一个负号：<span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^(0|-?[1-9][0-9]*)$</span>^(0|[1-9][ 0 -9]*)$

🎜🎜🎜A 0 atau nombor yang tidak bermula dengan 0. Kami juga boleh membenarkan tanda negatif pada permulaan: 🎜🎜^(0|-?[ 1-9 ][0-9]*)$🎜🎜

4 Ini bermakna 0 atau nombor yang mungkin negatif dan tidak bermula dengan 0. Biarkan pengguna bermula dengan 0. Juga buang tanda negatif, kerana wang tidak boleh menjadi negatif Apa yang akan kita tambahkan seterusnya ialah bahagian perpuluhan yang mungkin: <span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^[0-9]+(.[0-9]+)?$</span>

必须说明的是,小数点后面至少应该有1位数，所以”10.”是不通过的,但是 “10” 和 “10.2” 是通过的：<span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^[0-9]+(.[0-9]{2})?$</span>^[0-9]+(.[0-9]+)?$

🎜🎜🎜Perlu diingatkan bahawa perlu ada sekurang-kurangnya 1 digit selepas nombor titik perpuluhan, jadi "10." tidak diluluskan, tetapi "10" dan "10.2" diluluskan: 🎜🎜^[0-9]+(.[0-9]{2})?$ 🎜 🎜

Dengan cara ini kami menetapkan bahawa mesti ada dua tempat perpuluhan selepas titik perpuluhan Jika anda rasa ia terlalu keras, anda boleh melakukan ini: <code mp-original-font-size="14.449999809265137" mp-original-line-height="23" style="margin: 0px 0.15em;padding: 0px 0.3em;outline: 0px;max-width: 100%;font-size: 14.45px;font-family: Consolas, Inconsolata, Courier, monospace;white-space: pre-wrap;border-width: 1px;border-style: solid;border-color: rgb(234, 234, 234);background-color: rgb(248, 248, 248);border-radius: 3px;display: inline;line-height: 23px;box-sizing: border-box !important;overflow-wrap: break-word !important;"><span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^[0-9]+(.[0-9]{1,2})?$</span>^[0-9]+(.[0-9 ]{1,2})?$

🎜

Ini membolehkan pengguna menulis hanya satu tempat perpuluhan. Seterusnya kita harus mempertimbangkan nombor <span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">逗号</span> 了，我们可以这样：<span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^[0-9]{1,3}(,[0-9]{3})*(.[0-9]{1,2})?$</span>koma

🎜 Sekarang, kita boleh melakukan ini: 🎜🎜^[0-9]{ 1 ,3}(,[0-9]{3})*(.[0-9]{1,2})?$🎜🎜

1到3个数字,后面跟着任意个 逗号+3个数字，逗号成为可选，而不是必须：<span mp-original-font-size="16" mp-original-line-height="25" style="margin: 0px;padding: 0px;outline: 0px;max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;font-size: 16px;overflow-wrap: break-word !important;line-height: 25px;">^([0-9]+|[0-9]{1,3}(,[0-9]{3})*)(.[0-9]{1,2})?$</span>

备注：这就是最终结果了,别忘了+可以用*替代如果你觉得空字符串也可以接受的话(奇怪,为什么?)最后,别忘了在用函数时去掉去掉那个反
